1. ROBERTO BETIM PAES LEME. [en] CONSUMPITION AND TRANSFORMATION OF SURFING IMAGE.

Degree: 2018, Pontifical Catholic University of Rio de Janeiro

[pt] O estudo propõe uma possível relação entre o discurso editorial e o publicitário na formação de uma imagem sobre a prática do surfe presente em nosso cotidiano. Mais especificamente, o trabalho apresenta uma reflexão sobre a construção dessa prática a partir de quem vive e consome os produtos vinculados a ela. Sendo assim, um método de pesquisa com viés antropológico foi desenvolvido. Após observar o surfe na publicidade, analisamos as publicações especializadas no sentido de compreender o que e para quem dizem os editores de tais veículos. Acreditamos que ao observar costumes e hábitos sob o prisma do consumo, podemos encontrar pistas importantes para entender o indivíduo e o design para o qual tais publicações se dirigem. Entendemos, por fim, que a prática do surfe à qual se faz referência ao longo do texto, carrega consigo elementos importantes na caracterização desse indivíduo.

[en] The study proposes a possible relationship between the publishing and the advertising discourses in the idealization an image of the practice of surfing present in everyday life. More specifically, the work presents a reflection on the construction of this practice from those who live and consume products tied to it. Therefore, a research method with anthropological aproach was developed. After observing the surfing in advertising, specialized publications were analyzed, in order to understand what and who the editors were aiming with each media. We observed that consumers life style and habits can give important clues to understand the design adapted in the studied graphic material. We believe that the practice of surfing, wich is referred throghout the text, carries important elements in characterization of this individual.

2. JAISSE GRELA ESCOBAR. [en] A TOOL FOR TRACKING VIDEOS AND IMAGES USING STEGANOGRAPHY TECHNIQUES.

Degree: 2016, Pontifical Catholic University of Rio de Janeiro

[pt] Na indústria de TV frequentemente ocorrem vazamentos de materiais de filmagem quando estes se distribuem entre os colaboradores de produção, prejudicando grandemente as empresas. Neste trabalho propomos uma ferramenta que, utilizando técnicas de esteganografia adaptativa, permite detectar a fonte do vazamento com um elevado grau de confiança. Um requisito importante é que a informação mascarada no vídeo (ou na imagem) resista a operações de processamento tais como redimensionamento e mudança de resolução. A ideia é usar o algoritmo Speeded Up Robust Features (SURF), estratégia consagrada, na detecção e descrição de características em imagens para detectar regiões robustas da imagem e inserir nelas uma pequena identificação mascarada. A ferramenta utiliza a transformada Haar – Discrete Wavelet Transform em duas dimensões, para depois fazer modificações na imagem. Esta dissertação propõe direções iniciais promissoras para a identificação segura de certificados de origem de imagens e vídeos.

[en] In the TV industry, leaks of film materials occur frequently when they are distributed among the members of the production team, causing great harm to the companies. In this paper, we propose a tool that allows detecting the source of the leak with a high degree of confidence, using techniques of adaptive steganography. An important requirement is that the information embedded in the video (or image) should resist to processing operations such as resizing and resolution changes. The idea is to use the Speeded Up Robust Features (SURF) algorithm, a well-known strategy for detection and description of images features, to detect the robust regions of the image and insert a small masked identification in them. The tool uses the Haar - Discrete Wavelet Transform in two dimensions and then modifies the image. This dissertation proposes promising initial directions for secure identification of the certificate of origin of digital images and videos.

3. Mokhtari, Djamila. Détection des chutes par calcul homographique .

Degree: 2012, Université de Montréal

La vidéosurveillance a pour objectif principal de protéger les personnes et les biens en détectant tout comportement anormal. Ceci ne serait possible sans la détection de mouvement dans l’image. Ce processus complexe se base le plus souvent sur une opération de soustraction de l’arrière-plan statique d’une scène sur l’image. Mais il se trouve qu’en vidéosurveillance, des caméras sont souvent en mouvement, engendrant ainsi, un changement significatif de l’arrière-plan; la soustraction de l’arrière-plan devient alors problématique. Nous proposons dans ce travail, une méthode de détection de mouvement et particulièrement de chutes qui s’affranchit de la soustraction de l’arrière-plan et exploite la rotation de la caméra dans la détection du mouvement en utilisant le calcul homographique. Nos résultats sur des données synthétiques et réelles démontrent la faisabilité de cette approche. Advisors/Committee Members: Meunier, Jean (advisor).
