▼ SVENSKA: Vårt kandidatarbete gick ut på att ta reda på om det var möjligt att utveckla ett kort spel i hög teknisk kvalitet och ändå skapa ett djupt intryck på spelaren. Under projektets gång utvecklade vi, med hjälp av UDK (Unreal Development Kit), ett skräckspel i 3D till PC vid namn The Horror at MS Aurora. För att erhålla den höga tekniska kvaliteten som vi var ute efter användes metoder som räknas som standard för stora speltitlar på marknaden: Animationer spelades in med Motion Capture och musiken skrevs med en full symfoniorkester i åtanke. Innan produktionsfasen tog vid gick alla gruppmedlemmarna igenom en research-fas, där var och en satte sig in i de områden som skulle komma att vara aktuella under produktionen (d.v.s. hur UDK fungerar, musikteori och orkestrationsteknik, hur man arbetar med Motion Capture-data o.s.v.). Planering inför produktionen skedde med hjälp av vattenfallsmetoden och arbetsschemat sattes up med hjälp av ett så kallat Gantt-schema (detta diskuteras i detalj i kapitel 3). Vid inlämningen för kandidatarbetet hade arbetsgruppen hunnit skapa en kort bit av spelet som visade ungefär hur slutprodukten skulle komma att se ut. Spelet är tänkt att släppas på den digitala distributionsplattformen Steam mot slutet av sommaren 2011. ENGLISH: The goal of our bachelor thesis was to find out whether or not it was possible to create a high quality game with a short play time which would cause a deep emotional impact on the player. During the course of the project we, with the help of UDK (Unreal Development Kit), created a 3D horror game for the PC called The Horror at MS Aurora. To achieve the high quality we needed we used methods that are standard fare for the big games on the market: Animations were recorded using Motion Capture and the music was composed with a full symphonic orchestra in mind. Before the production phase began, each team member gathered research relevant to his field (i.e. how UDK works, music theory and orchestration, how to handle Motion Capture data and so on). We used the waterfall model and a Gantt chart when planning development (more on this in chapter 3). When we handed in the project for review we had managed to create a short piece of the game that showed – roughly – what the final product would look and feel like. The game is planned for release on the digital distribution platform Steam at the end of summer, 2011.

▼ A camera is a device for compressing rich information about the visual appearance of the three-dimensional world into a two-dimensional image. This process is inherently lossy: given an image, we can make educated guesses about the world's shape and appearance, but there is not enough information for our guesses to be certain. However, if we take several pictures from different viewpoints we can reason more confidently. This thesis focuses on shape: How can we determine the geometry of the world from a collection of photos? This problem is classically called Structure from
Motion. We find the structure (shape of the world) from camera
motion (different viewpoints). Internet photo collections are an especially interesting source of data. With simple searches we can collect the raw information to reconstruct
3D models of famous world landmarks or entire cities. However, the photos we download are disorganized and noisy, and will not have been collected with
3D reconstruction in mind. While some impressive demonstrations of Structure from
Motion systems exist, the next generation of solvers will need to be far more robust to the many types of difficulties encountered in the wild. To this end, many recent solvers pose the problem in a new way, using relative relationships between images to infer first the orientations, and then the positions of every camera in a scene. This framework promises faster runtime and greater robustness. I contribute a theoretical analysis of the difficulty of finding camera orientations, giving a way to decide which problems are tractable and which ones might be too hard and should be reformulated. I also propose a new solver with an accompanying outlier filter for finding camera positions. However, some of the hardest scenes are those which contain ambiguous structures: objects that look the same but are not. These induce self-consistent errors which are often too confusing for solvers to resolve correctly. I describe a scalable system which uses a graph-topological cue from a visibility graph to detect and remove these sources of error. Together these improvements work towards a robust solution to the Structure from
Motion problem, so that we can reliably build
3D models of the world, even from noisy and confusing internet photo collections.

▼ This thesis focuses on improving the accuracy of using multiple-shot fringe projection profilometry (FPP) for three dimensional (3D) shape measurement of rigid objects with movement. By using information on the object movement, the errors caused by the object movement in the projection of the multiple fringe patterns are addressed. The author mathematically describes the movement of the rigid object using a rotation matrix and translation vector. The influence on the fringe patterns caused by the movement is then analysed. Because the movement of the object changes the height distribution of the object surface, and the height distribution is related to the captured fringe patterns, a new expression for fringe patterns with movement is obtained. Using the new expression, algorithms are proposed to address the errors caused by different types of movement. At last, the errors caused by the object movement are removed successfully.
At the beginning of this thesis, an algorithm based on phase-shifting profilometry (PSP) is proposed to address the errors caused by the two dimensional (2D) movement of the object. Firstly, the rotation matrix and the translation vector describing the movement of the object are estimated using a set of marks placed on the surface of the object. New expressions for the fringe patterns under the influence of the 2D object movement are then derived and used to determine the correct phase map, which leads to accurate measurement of the object profile.
Because the intensity ratio method with a triangular fringe pattern can be more efficiently calculated than the phase value in PSP, an algorithm based on the intensity ratio method is proposed to address the errors caused by 2D movement. The movement of the object is described by the rotation matrix and the translation vector. The influence on the fringe patterns caused by the 2D movement of the object is then analysed and then used to estimate the normalised fringe patterns from the object without movement. Finally, the object is reconstructed by using the existing intensity ratio algorithm and incorporating the estimated fringe patterns, which leads to improved measurement accuracy.
In practice, the movement of an object is not limited to two dimensions. Therefore, a third algorithm based on PSP is proposed to address the errors when the object is subject to 3D movement. Because 3D movement introduces unknown height variation of the object, the algorithms used to account for 2D movement become invalid. An iterative least-squares algorithm is proposed to address the errors caused by the 3D movement. The object is limited to be a rigid object, and the movement consists of a translation in the direction of height and a 2D movement in the plane perpendicular to the direction of height. The proposed method does not require the height variation caused by the movement to be known in advance.
The thesis also addresses the errors caused by the shadow in PSP. Because the shadow areas in the captured image do not include the…

▼ This research project has two main aims. The first is to investigate why digital cyber stars in recent live action movies have not always been widely accepted by audiences, despite being rendered to look photo-real and animated using
motion capture. The second is to investigate possible pipeline integration issues as well as any creative concerns that arise when utilising
motion captured data to generate movement for stylised characters. These observations are made through the creation of an animated short which integrates
motion captured movement with non photo-real, caricatured digital actors. The short, titled Perhaps, Perhaps, Perhaps, features four characters and is created in the form of a music video.

▼ The visual system supports perception and inferences about events in a dynamic, three-dimensional (
3D) world. While remarkable progress has been made in the study of visual information processing, the existing paradigms for examining visual perception and its relation to neural activity often fail to generalize to perception in the real world which has complex dynamics and
3D spatial structure. This thesis focuses on the case of
3D motion, developing dynamic tasks for studying visual perception and constructing a neural coding framework to relate neural activity to perception in a
3D environment.
First, I introduce target-tracking as a psychophysical method and develop an analysis framework based on state space models and the Kalman filter. I demonstrate that target-tracking in conjunction with a Kalman filter analysis framework produce estimates of visual sensitivity that are comparable to those obtained with a traditional forced-choice task and a signal detection theory analysis. Next, I use the target-tracking paradigm in a series of experiments examining
3D motion perception, specifically comparing the perception of frontoparallel
motion with the perception of
motion-through-depth. I find that continuous tracking of
motion-through-depth is selectively impaired due to the relatively small retinal projections resulting from
motion-through-depth and the slower processing of binocular disparities.
The thesis then turns the neural representation of
3D motion and how that underlies perception. First I introduce a theoretical framework that extends the standard neural coding approach, incorporating the environment-to-retina transformation. Neural coding typically treats the visuals stimulus as a direct proxy for the pattern of stimulation that falls on the retina. Incorporating the environment-to-retina transformation results in a neural representation fundamentally shaped by the projective geometry of the world onto the retina. This model explains substantial anomalies in existing neurophysiological recordings in primate visual cortical neurons during presentations of
3D motion and in psychophysical studies of human perception. In a series of psychophysical experiments, I systematically examine the predictions of the model for human perception by observing how perceptual performance changes as a function of viewing distance and eccentricity. Performance in these experiments suggests a reliance on a neural representation similar to the one described by the model.
Taken together, the experimental and theoretical findings reported here advance the understanding of the neural representation and perception of the dynamic
3D world, and adds to the behavioral tools available to vision scientists.

▼ Ce travail se divise en deux parties : la première partie consiste à développer et valider une technique d’exploration de la fonction respiratoire à l’aide d’outils de capture du mouvement de la cage thoracique et de l’abdomen en trois dimensions. L’innovation consiste en l’application d’une méthode de calcul des volumes pulmonaires mobilisables non encore utilisée avec cette technique. La deuxième partie consiste à mettre en évidence l’intérêt médical de cette technique par son utilisation clinique sur des pathologies respiratoires ciblées et/ou dans des conditions médicales spécifiques. Dans un premier temps et suite à une analyse de la littérature des méthodes d’exploration de la fonction respiratoire par mesure optoélectronique,nous avons proposé une nouvelle méthode de calcul des volumes respiratoires à partir de capture de mouvement de la paroi thoracoabdominale.Cette méthode prend en compte les déplacements de la surface de la paroi thoracoabdominale. Une comparaison entre cette nouvelle méthode,la méthode optoélectronique habituellement utilisée et la spirométrie(méthode de référence) montre que cette nouvelle méthode permet une évaluation précise des volumes respiratoires. Dans un second temps,une fois la question métrologique de mesure suffisamment précise des volumes validés, nous nous sommes intéressés à l’intérêt clinique d’apprécier la contribution des différents compartiments de la paroi thoracoabdominaleà la ventilation des patients myopathes et des sujets sous ventilationmécanique. Une première étude sur une population de patients présentant une déficience en maltase acide, visant l’identification du dysfonctionnement diaphragmatique a été réalisée. Ainsi nous avons pu démontrer que la contribution de la région abdominale à la ventilation est corrélée avec les indices invasifs évaluant la fonction diaphtragmatique. Cela nous permet maintenant de suivre l’évolution de la fonction diaphragmatique de ces patients de manière non invasive. Une seconde étude visait l’analyse de la contribution abdominale de la ventilation lorsque cette dernière est assistée mécaniquement. Ainsi nous avons pu observer que la ventilation mécanique diminuait la contribution abdominale, quel que soit le mode d’assistance ventilatoire utilisé, ce qui suggère une diminution de l’activité diaphragmatique sous ventilation mécanique et donc de confirmer une efficacité de ventilation mécanique. Une troisième étude sur le patient atteint de la myopathie de Duchenne de Boulogne a permis de quantifier les effets à court terme des manoeuvres d’insufflation et d’exsufflation sur la mobilité non assistée de la cage thoracique. Ainsi nous avons observé, immédiatement après ces manoeuvres, une meilleure expansion et une symétrisation de cette expansion thoracoabdominale lors d’inspirations et d’expirations maximales. Cela plaide pour une utilisation plus systématique de ces techniques au quotidien lors de la prise en charge de cette population, en particulier pour ceux qui présentent une dysharmonie du mouvement thoracoabdominal.Ce travail…

▼ Structure-from-Motion (SfM) is a powerful tool for computing 3D reconstructions from images of a scene and has wide applications in computer vision, scene recognition, and augmented and virtual reality. Standard SfM pipelines make strict assumptions about the capturing devices in order to simplify the process for estimating camera geometry and 3D structure. Specifically, most methods require monocular cameras with known focal length calibration. When considering large-scale SfM from internet photo collections, EXIF calibrations cannot be used reliably. Further, the requirement of single camera systems limits the scalability of SfM. This thesis proposes to remove these constraints by instead considering the collection of cameras as a distributed camera that encapsulates the image and geometric information of all cameras simultaneously. First, I provide full generalizations to the relative camera pose and absolute camera pose problems. These generalizations are more expressive and extend the traditional single-camera problems to distributed cameras, forming the basis for a novel hierarchical SfM pipeline that exhibits state-of-the-art performance on large-scale datasets. Second, I describe two efficient methods for estimating camera focal lengths for the distributed camera when calibration is not available. Finally, I show how removing these constraints enables a simpler, more scalable SfM pipeline that is capable of handling uncalibrated cameras at scale.

▼ Les environnements virtuels collaboratifs permettent à plusieurs utilisateurs d’interagir à distance par Internet. Ils peuvent partager une impression de téléprésence en animant à distance un avatar qui les représente. Toutefois, le contrôle de cet avatar peut être difficile et mal restituer les gestes de l’utilisateur. Ce travail vise à animer l’avatar à partir d’une acquisition 3D des gestes de l’utilisateur par vision monoculaire en temps réel, et à rendre la téléprésence virtuelle possible au moyen d’un PC grand public équipé d’une webcam. L’approche suivie consiste à recaler un modèle 3D articulé de la partie supérieure du corps humain sur une séquence vidéo. Ceci est réalisé en cherchant itérativement la meilleure correspondance entre des primitives extraites du modèle 3D d’une part et de l’image d’autre part. Le recalage en deux étapes peut procéder sur les régions, puis sur les contours. La première contribution de cette thèse est une méthode de répartition des itérations de calcul qui optimise la robustesse et la précision sous la contrainte du temps-réel. La difficulté majeure pour le suivi 3D à partir d’images monoculaires provient des ambiguïtés 3D/2D et de l’absence d’information de profondeur. Le filtrage particulaire est désormais une approche classique pour la propagation d’hypothèses multiples entre les images. La deuxième contribution de cette thèse est une amélioration du filtrage particulaire pour le recalage 3D/2D en un temps de calcul limité par des heuristiques, dont la contribution est démontée expérimentalement. Un paramétrage de l’attitude des bras par l’extrémité de leur chaîne cinématique est proposé qui permet de mieux modéliser l’incertitude sur la profondeur. Enfin, l’évaluation est accélérée par calcul sur GPU. En conclusion, l’algorithme proposé permet un suivi 3D robuste en temps-réel à partir d’une webcam pour une grande variété des gestes impliquant des occlusions partielles et des mouvements dans la direction de la profondeur.
Networked 3D virtual environments allow multiple users to interact with each other over the Internet. Users can share some sense of telepresence by remotely animating an avatar that represents them. However, avatar control may be tedious and still render user gestures poorly. This work aims at animating a user’s avatar from real time 3D motion capture by monoscopic computer vision, thus allowing virtual telepresence to anyone using a personal computer with a webcam. The approach followed consists of registering a 3D articulated upper-body model to a video sequence. This involves searching iteratively for the best match between features extracted from the 3D model and from the image. A two-step registration process matches regions and then edges. The first contribution of this thesis is a method of allocating computing iterations under real-time constrain that achieves optimal robustness and accuracy. The major issue for robust 3D tracking from monocular images is the 3D/2D ambiguities that result from the lack of depth information. Particle filtering has…

▼ O projeto “À Descoberta das Ilhas” surge das lacunas de atenção e motivação por parte das crianças na realização de exercícios na terapia ocupacional, aliadas a uma subjetividade na análise do seu progresso.
Direcionado para crianças com dificuldades de integração bilateral motora, com idades compreendidas entre os cinco e nove anos, este projeto tem como base um jogo 3D para as plataformas Windows, Mac OS X e Linux, controlado com os movimentos dos membros superiores através do dispositivo Leap Motion. Através do controlo de um avião, a criança descobre várias ilhas e desbloqueia componentes do mesmo, alcançando os diversos bónus e checkpoints ao longo de cada percurso. Ao terapeuta são apresentados gráficos com dados obtidos pelo dispositivo aquando do momento lúdico da criança que permitem acompanhar a sua evolução a cada nível.
O sucesso no cumprimento dos objetivos do projeto permitiu confirmar a utilidade da aplicação na intervenção e avaliação do público-alvo.
The project “À Descoberta das Ilhas” comes from the lack of attention and motivation in children when preforming the traditional exercises in occupational therapy sessions, furthermore, the analysis of their progress is based on subjectivity.
Aimed at the children with bilateral motor integration difficulties, aged between five and nine years, this project is based on a 3D game for Windows, Mac OS X and Linux platforms, that is controlled by the upper limb’s movements through the Leap Motion device. By controlling a plain, the child is able to discover several islands and unlock plain’s components, achieving bonus and several checkpoints along each journey. Graphs with data obtained by the device are then presented to the therapist enabling him monitoring and evaluation the child’s performance.
The success in meeting the objectives of the project confirmed the usefulness of the application in the assessment and intervention of the target audience.

▼ Táto práca sa zaoberá metódami snímania podpisov v
3D priestore, výberom vhodného modelu snímania, získaním dostatočného počtu vzoriek na vytvorenie databázy a nakoniec overovaním podpisov. V prvej časti je spracovaná problematika existujúcich riešení a spôsobov overovania podpisov, ďalej spracovanie obrazu potrebné pre účely snímania markeru v
3D priestore. Nasledujúce časti sú venované návrhu unikátneho riešenia podpisovania sa v priestore perom absenciou akéhokoľvek kontaktu. Boli navrhnuté dva modely snímania a to pomocou kamier alebo senzoru Leap
Motion. Aplikácia bola implementovaná nad týmto senzorom a systém overovania dynamických podpisov pomocou algoritmu DTW. Ďalej práca obsahuje popis vytvorenia databázy a experimentálne overenie podpisov. Na konci nájdeme zhodnotenie bezpečnosti a chybovosti systému, ktoré je porovnané s inými metódami. Výsledkom práce je funkčná aplikácia na snímanie a rozpoznávanie
3D podpisov s potenciálom novej bezpečnej techniky podpisovania.; This work deals with methods of signing in
3D space, selecting a suitable scan model, obtaining a sufficient number of samples to create a database, and finally verifying signatures. The first part deals with the issue of existing solutions and methods of signature verification, further image processing required for marker shooting in
3D space. The following sections are dedicated to design a unique signature solution in free space using a pen without any contact. Two shooting models have been designed using cameras or Leap
Motion sensor. The application was implemented based on DTW algorithm using this sensor resulting in a dynamic signature verification system. Furthermore, the work includes a description using of database creation and experimental signature verification. At the end, we find an assessment of the security and error rate of the system that is compared to other methods. The result of this thesis is an application for
3D signature capture and recognition with the potential of a new technique for secure signature.

▼ Cílem této práce bylo vytvoření jednoduché aplikace pro
3D kreslení pomocí senzoru Leap
Motion. Na této aplikaci byla testována efektivita interakce s rozhraním gesty oproti interakci kombinované s klávesou. Testováním bylo zjištěno, že ovládání kreslení gestem není tak efektivní jako klávesou. Nicméně po delší interakci uživatelů s aplikací se projevilo znatelné zrychlení ve prospěch aktivace gestem.; The goal of this thesis was to create a simple
3D drawing application that uses Leap
Motion controller. This application was designed to test gesture-based interaction versus keyboard controls. It was found that gesture-based interaction is not as effective as interaction combined with keyboard. However, when users interact with the application for a prolonged period of time, the noticeable acceleration of gesture-based interaction could be observed.

▼ A key problem in mobile computing is providing people access to necessary cyber-information associated with their surrounding physical objects. Mobile augmented reality is one of the emerging techniques that address this key problem by allowing users to see the cyber-information associated with real-world physical objects by overlaying that cyber-information on the physical objects's imagery. As a consequence, many mobile augmented reality approaches have been proposed to identify and visualize relevant cyber-information on users' mobile devices by intelligently interpreting users' positions and orientations in
3D and their associated surroundings. However, existing approaches for mobile augmented reality primarily rely on Radio Frequency (RF) based location tracking technologies (e.g., Global Positioning Systems or Wireless Local Area Networks), which typically do not provide sufficient precision in RF-denied areas or require additional hardware and custom mobile devices.
To remove the dependency on external location tracking technologies, this dissertation presents a new vision-based context-aware approach for mobile augmented reality that allows users to query and access semantically-rich
3D cyber-information related to real-world physical objects and see it precisely overlaid on top of imagery of the associated physical objects. The approach does not require any RF-based location tracking modules, external hardware attachments on the mobile devices, and/or optical/fiducial markers for localizing a user's position. Rather, the user's
3D location and orientation are automatically and purely derived by comparing images from the user's mobile device to a
3D point cloud model generated from a set of pre-collected photographs.
A further challenge of mobile augmented reality is creating
3D cyber-information and associating it with real-world physical objects, especially using the limited 2D user interfaces in standard mobile devices. To address this challenge, this research provides a new image-based
3D cyber-physical content authoring method designed specifically for the limited screen sizes and capabilities of commodity mobile devices. This new approach does not only provide a method for creating
3D cyber-information with standard mobile devices, but also provides an automatic association of user-driven cyber-information with real-world physical objects in
3D.
Finally, a key challenge of scalability for mobile augmented reality is addressed in this dissertation. In general, mobile augmented reality is required to work regardless of users' location and environment, in terms of physical scale, such as size of objects, and in terms of cyber-information scale, such as total number of cyber-information entities associated with physical objects. However, many existing approaches for mobile augmented reality have mainly tested their approaches on limited real-world use-cases and have challenges in scaling their approaches. By designing fast direct 2D-to-
3D matching algorithms for localization, as well as applying caching…

▼ Depth camera relies on its three-dimensional information capture capabilities and low prices, has been widely used in many areas, such as consumer, gaming, education, robotics and medical rehabilitation. The medical rehabilitation project has attracted attention, and some company has launched the products with depth cameras for rehabilitation activities. According to the World Health Organization (WHO) survey, more than a billion people, about 15 percent of the population, should rehabilitate worldwide. An effective rehabilitation process is needed to cope with such a great number of people. In this thesis, a
3D virtual guidance system is designed to assist human to accomplish rehabilitation. It integrates the
3D virtual characters and depth camera information so patients can view their own movements. The rehabilitation mode includes general rehabilitation and recreational activities. In the General Rehabilitation mode, if the patient moves to the wrong direction, the guidance will appear on the screen. It can help patients to correct errors. And recreational activities enhance the patientâs rehabilitation will. The experimental results show that the system has been highly praised by the subjects. It is a practical system with high availability.

▼ Reconstrução
3D é uma área de pesquisa que engloba várias técnicas com o
propósito de recuperar modelos que representem precisamente um objeto ou um cenário
em três dimensões, enfatizando características de interesse como, por exemplo, a forma, a
textura ou a estrutura. O cerne de algoritmos de Struture from
Motion (SfM), que é um tipo
de técnica de reconstrução
3D bastante promissor, visa a obtenção da geometria
3D da cena
a partir de um conjunto de imagens bidimensionais, além da posição e orientação da
câmera no momento da captura. Para cada par de imagens é possível estimar a
profundidade de um ponto conhecendo-se os parâmetros intrínsecos e extrínsecos da
câmera e as coordenadas bidimensionais referentes a um mesmo ponto em cada foto,
apesar de não ser possível determinar o tamanho real do objeto. Além disso, cada par de
imagens produz uma reconstrução em um sistema de coordenadas distinto. Portanto,
devido a essa falta de escala uniforme e das câmeras estarem em bases diferentes, é
necessária a utilização de algoritmos que levem as câmeras para uma mesma base de
referência, ou seja, que alinhem as câmeras e que criem uma reconstrução completa, pois,
há pontos em algumas imagens que não são contemplados por outras.
Esta dissertação de mestrado descreve os esforços empregados na investigação dos
principais algoritmos de alinhamento, sua implementação e o aperfeiçoamento dos mesmos
quando necessário, além de identificar o quão preciso é cada método. Entre as técnicas
propostas na literatura foram utilizadas quatro abordagens, uma baseada na composição
das matrizes de pose, duas baseadas na matriz de homografia e uma na correspondência
entre os pontos 2D e os pontos
3D. Cada algoritmo se baseia em diferentes técnicas que
resultam em matrizes de câmera distintas que ao serem fatoradas definem uma translação e
a rotação semelhante. A fim de melhorar a precisão dos resultados gerados, foi utilizado o
Sparse Bundle Adjustment (SBA) ao final de cada método. Para analisar os algoritmos, foi
definida uma metodologia de comparação com métricas que avaliam os resultados não só
qualitativamente como quantitativamente. Os critérios propostos foram a comparação dos
pontos reconstruídos com o ground-truth, a análise dos erros de projeção e epipolar, as
poses das câmeras e o tempo de execução. A metodologia foi aplicada tanto para dados
sintéticos quanto para dados reais e, todos obtiveram resultados visualmente coerentes.
Porém, a técnica de 2D3D se mostrou com resultados mais precisos

▼ A reconstrução
3D é uma área de pesquisa que consiste em recuperar modelos que representem com precisão e em
3D características de interesse de uma cena, através da extração de informações
3D a partir de imagens 2D. Estas informações podem ser relativas à estrutura de uma determinada cena, posicionamento e trajetória de câmeras, textura, dentre outras. Uma vez de posse de tais informações, podemos utilizá-las para os mais diversos fins, por exemplo, modelagem automática de objetos, sistemas de navegação autônoma de robôs, modelos computacionais de estruturas ou órgãos do corpo humano, posicionamento de elementos virtuais em cenas reais, dentre outros.
Uma das formas mais difundidas de se realizar reconstrução
3D é utilizando sequências contíguas de imagens ou vídeos capturados por câmeras convencionais (monoculares). Neste tipo de reconstrução um dos desafios mais importantes é o rastreamento. Rastreamento é a capacidade de conseguir corresponder um conjunto de pontos em uma sequência de imagens, ou seja, dado um ponto A com coordenadas x e y, deve-se ser capaz de identificar o ponto A com coordenadas x e y na imagem seguinte da sequência, e que corresponde exatamente à mesma localidade da estrutura sendo rastreada.
Neste contexto, o objetivo desta dissertação de mestrado foi avaliar os algoritmos de rastreamento mais utilizados para este propósito, ressaltando as características individuais de cada um deles e identificando as vantagens e limitações que possuem. Os resultados desta análise podem ser uma ferramenta de auxílio na escolha do algoritmo de rastreamento a ser utilizado quando do desenvolvimento de uma solução de reconstrução
3D, tendo como base o domínio do problema que se deseja atacar.
Os três algoritmos analisados foram o SIFT, o KLT e outro Baseado em Similaridade. Foi desenvolvida uma ferramenta de reconstrução
3D baseada em SfM. Esta ferramenta foi utilizada para a coleta de resultados com o rastreamento sendo realizado com SIFT, KLT e Similaridade. Uma etapa importante deste processo foi a definição de um conjunto de métricas para a análise comparativa dos algoritmos. As características individuais de rastreamento de cada um deles trouxeram bons resultados em alguns dos cinco cenários utilizados. Porém, no geral, o rastreador que apresentou os melhores resultados foi o KLT. Uma análise detalhada sobre os resultados desses algoritmos quando empregados para reconstrução
3D é apresentada

▼ Photogrammetry is playing more important role in many industries today, and thanks to Structure-from-
Motion,
3D point clouds and
3D meshes can be produced and be used as a resource for surveying and documentation.
In this project, the accuracies of Structure-from-
Motion generated point clouds from pictures taken from different distances are assessed to determine if the distance has a significant impact on the accuracy and what kind of pattern the accuracies will show if there is any. Due to space limit, an improvised turntable was used in order to mimic the condition where camera moves around the object. Multiple images were collected from different distances and corresponding point clouds were generated using Agisoft Photoscan. Using the generated point clouds, accuracy assessment was able to be carried out.
During the analysis, other than the impact of distance, a slight impact of different colors was found first visually and then also analyzed with similar method.

▼ The goal of this thesis is to develop a volumetric
display for portraying human body motions in real-time. The results
of three-dimensional motion analyses are typically displayed on a
two-dimensional video screen. While such views may be rotated to
give the appearance of a three dimensional motion, viewing a flat
screen is inherently different from a truly three-dimensional
display. A volumetric display would allow perception of the motion
in three true dimensions and multiple observers could
simultaneously view the same motion from different angles. Two
different approaches to volumetric displays were explored, an LED
display and a projected-light string display. The former is
controlled by a microcontroller that is programmed to light a 3-D
array of LEDs, and the latter involves projection of a
two-dimensional image onto an array of vertical strings to create
the three-dimensional image. Because it was less expensive to
fabricate and easier to interface with the motion capture system,
it was decided to move forward with the projected-light string
display. Using a six camera Eagle Motion System, the coordinates of
markers placed on human body segments were recorded and accessed in
MATLAB in real-time. The marker data were used to calculate
intersections between the body segments and the strings in the
display. These intersections were represented as rectangles in a
two-dimensional image projected onto the strings to create the
three-dimensional image. Three applications were developed to
demonstrate the capabilities of the display: (1) real-time posture
assessment and training; (2) feedback of trunk lean angles during
walking to lessen loads on painful joints; and (3) feedback of low
back loads during a lifting task. Preliminary data collected during
tests of these applications suggest that the use of the display
conveys benefits to motor learning. To evaluate these effects more
completely, further research is needed to compare the use of
volumetric displays to other forms of feedback commonly used to
enhance motor learning.

Dynamic Geometry Capture with a Multi-View Structured-Light System.

▼ Human Motion capture has been an active area of research for many years and has applications in many fields such as gaming, entertainment, physical therapy, and ergonomics. Most commercially available motion capture systems use numerous markers to be placed on the body of the human subject requiring a significant setup time. In this dissertation, we develop the architecture and algorithms for markerless motion capture with a multi-view structured light system. In contrast to existing markerless approaches that use multiple camera streams, we reconstruct the scene by combining the views from three structured light stations using sinusoidal phase shift patterns, each equipped with one projector, a stereo pair of cameras for phase unwrapping, and a color camera. The three stations surround the subject and are time multiplexed to avoid interference. Phase-shifted sinusoidal patterns offer low decoding complexity, require as few as three projection frames per reconstruction, and are well suited for capturing dynamic scenes. In these systems, depth is reconstructed by determining the phase projected onto each pixel in the camera and establishing correspondences between camera and projector pixels. Typically, multiple periods are projected within the set of sinusoidal patterns, thus requiring phase unwrapping on the phase image before correspondences can be established. There are three novel contributions to this dissertation; first, we present a novel phase unwrapping algorithm across space and time in order to generate a temporally consistent point cloud. Specifically, we combine a quality guided phase unwrapping approach with absolute phase estimates from the stereo cameras to solve for the absolute phase of connected regions. Second, we develop a calibration method for multi-camera-projector systems in which sensors face each other as well as share a common viewpoint. We use a translucent planar sheet framed in PVC piping as a calibration target which is placed at multiple positions and orientations within a scene. In each position, the target is captured by the cameras while it is being illuminated by a set of patterns from various projectors. The translucent sheet allows the projected patterns to be visible from both sides, allowing correspondences between devices that face each other. The set of correspondences generated between the devices using this target are input into a bundle adjustment framework to estimate calibration parameters. Third, we develop algorithms to reconstruct dynamic geometry of a human subject using a template generated by the system itself. Specifically, we deform the template to each frame of the captured geometry by iteratively aligning each bone of the skeleton. This is done by searching for correspondences between the source template and the captured geometry, solving for rotation of bones, and enforcing constraints on each rotation to prevent the template from taking on anatomically unnatural poses. Once the geometry of the dynamic mesh is reconstructed, the template is textured using the…

▼ We investigate two fundamental issues in Computer
Vision: 2D
motion segmentation and
3D dense shape reconstruction of
a dynamic scene observed from a moving camera. The scene contains
multiple rigid objects moving in a static background, while the
camera undergoes general
3D rotation and translation. Our goal is
to segment the video frames into 2D
motion regions and static
background areas, and then to reconstruct the dense
3D shape of
both parts of the scene.;
Motion segmentation of image sequences
shot by a moving camera is inherently difficult as the camera
motion induces a displacement for all the image pixels. This camera
motion is compensated for by a number of geometric constraints
estimated between video frames. The pixels that cannot be
compensated for by these constraints are classified as
motion
regions. A novel 3-view constraint is proposed to handle the cases
where existing ones do not work well. The geometric constraints are
combined in a decision tree based method for segmenting the
motion
regions from the background area in each video frame.; After
motion
segmentation, sparse
3D structure of the static background and
3D
camera
motion are estimated by the well-developed "Structure and
Motion (SaM)" methods.The same SaM methods are applied to recover
the
3D shape of moving objects from a moving camera, based on their
relative
motion. The object scale and
motion, however, can be only
solved up to an unknown scale, unless additional assumptions are
available. In our scenario, a planar-
motion assumption is
introduced: the object
motion trajectory must be parallel to a
plane. With the aid of the planar-
motion assumption, the
3D object
motion trajectory can be uniquely determined.; The sparse
3D
reconstruction of the dynamic scene is extended to a dense
volumetric one. The whole scene is divided into a set of volume
elements, termed as voxels. Each voxel is assigned an object label
which may change over time. The task of dense reconstruction is
then accomplished by a novel voxel coloring method that finds the
optimal label assignment for each voxel to minimize photo-
motion
variance measures between the voxels and the original
images.

▼ O presente projeto que aqui se apresenta ganhou o concurso “Passaporte para o
Empreendedorismo”
A Língua Gestual é um meio de comunicação entre surdos e entre surdos e técnicos
especialistas que não requer o uso da expressão/comunicação oral. Contudo, a interação de surdos com outras pessoas não surdas ou não especialistas é dificultada pela ausência de uma linguagem comum. Em particular, no contexto do dia-a-dia a utilização de serviços que envolvam uma interação mais complexa pode ser impossível sem um intérprete de Língua Gestual.
Com o intuito de resolver esta barreira na comunicação, foi vista uma oportunidade
de desenvolvimento de uma aplicação que, em conjunto com o Leap Motion, deteta, grava
e reconhece a fluência do movimento dos gestos na base da Língua Gestual.
Neste trabalho foram estudadas 4 diferentes metodologias com o intuito de iniciar o
desenvolvimento do primeiro tradutor pessoal de Língua Gestual Portuguesa (LGP) usando
a tecnologia recente e inovadora do Leap Motion. O trabalho foi desenvolvido sobre a
framework Unity3D por motivos de desenvolvimento futuro multiplataforma, o
desenvolvimento da interface de visualização gráfica em tempo real e a utilização de som
para a tradução.
Foram obtidos bons resultados em 3 das 4 metodologias, sendo elas o LeapTrainerUI,
e as duas aplicações de Reconhecimento de Numeração cardinal em LGP até 5, conseguindo
uma correta classificação da numeração. A última metodologia, Classificador de 1 Gesto,
com um grau de complexidade maior, foi a que obteve resultados menos satisfatórios.
Embora os resultados obtidos sejam preliminares, este trabalho abre as perspetivas ao desenvolvimento de um intérprete pessoal de LGP. Apesar desta língua ter uma complexidade superior à simples deteção de movimento das mãos e dos dedos, num futuro próximo, conseguir-se-á que pessoas surdas tenham consigo este dispositivo e consigam transmitir de forma verbalizada a sua intenção a pessoas que não entendam LGP.

▼ This thesis creates a short-form art piece primarily using modular
3D printed forms, photographed in a stop-
motion animation style, and composited digitally into a finished product. It creates the lab space needed to print and photograph the piece; including lighting, set, and photography equipment. This project shows that it is possible for a single artist to come up with sufficient time-saving techniques in order to complete an entire work from start to finish. This work also shows it is possible to create a work that will inspire the emotions of fear, horror, and frustration that comes with the birth of the new.

▼ One of the greatest challenges in achieving accurate positioning in head and neck radiotherapy is that the anatomy at and above the cervical spine does not act as a single, mechanically rigid body. Current immobilization techniques contain residual uncertainties that are especially present in the lower neck that cannot be reduced by setting up to any single landmark. The work presented describes the development of a radiotherapy friendly mostly-plastic 6D robotic platform for positioning independent landmarks, (i.e., allowing remote, independent positioning of the skull relative to landmarks in the thorax), including analysis of kinematics, stress, radiographic compatibility, trajectory planning, physical construction, and phantom measurements of correction accuracy. No major component of the system within the field of imaging or treatment had a measured attenuation value greater than 250 HU, showing compatibility with x-ray-based imaging techniques. Relative to arbitrary overall setup errors of the head (min = 1.1 mm, max = 5.2 mm vector error) the robotic platform corrected the position down to a residual overall error of 0.75 mm +/- 0.33 mm over 15 cases as measured with optical tracking. This device shows the potential for providing reductions to dose margins in head and neck therapy cases, while also reducing setup time and effort.

▼ Authentication plays a key role in securing various resources including corporate facilities or electronic assets. As the most used authentication scheme, knowledgebased authentication is easy to use but its security is bounded by how much a user can remember. Biometrics-based authentication requires no memorization but ‘resetting’ a biometric password may not always be possible. Thus, we propose study several behavioral biometrics (i.e., mid-air gestures) for authentication which does not have the same privacy or availability concerns as of physiological biometrics.
In this dissertation, we first propose a user-friendly authentication system Kin- Write that allows users to choose arbitrary, short and easy-to-memorize passwords while providing resilience to password cracking and password theft. Specifically, we let users write their passwords (i.e., signatures in the
3D space), and verify a user’s identity with similarities between the user’s password and enrolled password templates. Dynamic time warping distance is used for similarity calculation between
3D passwords samples.
In the second part of the dissertation, we design an authentication scheme that does not depend on the handwriting contents, i.e., regardless of the written words or symbols, and adapt challenge-response mechanism to avoid possible eavesdropping, man-in-the-middle attacks, and reply attacks. We design a MoCRA system that utilizes Leap
Motion to capture users’ writing movements and use writing style to verify users, even if what they write during the verification is completely different from what they write during the enrollment. Specifically, MoCRA leverages co-occurrence matrices to model the handwriting styles, and use a Support Vector Machine (SVM) to accept a legitimate user and reject the rest.
In the third part, we study both security and usability performance on multiple types of mid-air gestures that used as passwords, including writing signatures in the air. We objectively quantify the usability performance by metrics related to the enroll time and the complexity of the gestures, and evaluate the security performance by the authentication performance. In addition, we subjectively evaluate the gestures by survey responses from both field subjects who participated in gesture experiments and on-line subjects who watched a short video on gesture introducing. Finally, we study the consistency of gestures over samples collected in a two-month period, and evaluate their security under shoulder surfing attacks.

▼ The ancient country of China has a long history. It has many fascinating historical stories, historical figures, and an elaborate history. For people who want to learn about Chinese history it can often seem overwhelming.
I am planning to find an easy and interesting approach for people who are interested in learning about Chinese history. The effective approach to communicate to people could be enhanced visuals depicting the rich his€tory of China.
Out of this long history, I decided to reproduce a Chinese ancient heroic figure with
3D graphics tech€nology. I will achieve this by using
3D modeling technology, using nCloth, particles, fur, lighting, and rendering to cre€ate an ancient Chinese hero, and historic environment. I will create
3D animation, and use
motion graphics to make the beginning and end pieces for historical scenes. This piece of scene will display a realistic historic story; with two main characters (the hero and his wife) in this project.

▼ This study examined the acute effects of whole-body corrective exercise on postural alignment in a sample of 50 male participants (18-30 y) displaying asymmetrical postural deviations. All participants were randomly assigned to either a non-exercise control (n = 25) or corrective exercise treatment (n = 25) group. A three-dimensional motion analysis Vicon system was employed to quantify standing postural alignment at the beginning and end of a 6 d study. Postural misalignments were determined in degrees of symmetry (tilt) and rotation using horizontal and vertical virtual plumb lines for the following locations: hip (ASIS), leg (greater trochanter), shoulder (acromion process), and head (ear). The treatment group completed five corrective exercise sessions on separate days which included 11 exercises (requiring about 60 min per session to complete). The control group performed no intervention and maintained a normal lifestyle. At the commencement of the study there were no significant differences in the degree of postural misalignment between the control and treatment groups at any of the postural measurements. At the conclusion of the treatment period (following the five sessions of corrective exercise), there were no significant differences in any of the postural alignments of any of the postural measurements between the treatment and control groups. For example, all of the following postural measurements were not significantly different (critical F ≥ 4.24;df = 1,25) between groups: hip (ASIS) tilt (F = 0.05), hip (ASIS) rotation (F = 0.15), greater trochanter tilt (F = 1.58), greater trochanter rotation (F = 0.33), shoulder tilt (F = 2.63), shoulder rotation (F = 0.07), head tilt (F = 2.39), and head rotation (F = 2.79). The results of this study suggest that five sessions of corrective exercise were insufficient to significantly improve standing postural alignment. In addition, this study appears to be the first to document whole-body postural alignment using 3D video analysis.
