5. Reconhecimento de ações com histogramas de características visuais e contexto adicionado por tranferência de aprendizagem
This thesis addresses the task of recognizing human actions in realistic videos based on their visual content. Such an ability has a wide variety of applications in specic settings, but this work is above all motivated by the idea that efective visual descriptors and models need to be provided in order to make current search engines better able to cope with

6. Análise de desempenho no uso de pré-busca para distribuição de vídeo sobre redes P2P
Peer-to-Peer Video on Demand Systems have well stabilished its importance in recent years. Such consolidation is due to the high gains that may be archieved in terms savings in transmission bandwidth of the servers. In this work, we evaluate how this technology can enhance the gains for the transmission of continuous media over the Internet. To achieve this

7. Object tracking from compressed video using Kalman Filter and a novel spatiotemporal motion-vector filter.
Video Object Tracking plays a crucial role on several Computer Vision applications, such as Video Surveillance, Intelligent Transportation System (ITS), Human Machine Interface (HMI), Video Indexing and Shopping Behavior Analysis. Nevertheless, the processing power demanded by object tracking techniques still consists in a bottleneck to their wider adoption.

8. Controle de acesso baseado em biometria facial
Face recognition is one of the most ordinary and natural task carried out by humans. Even though it is a simple task, it has proved to be a major challenge for artificial intelligence and computer vision researchers. Researches on object detection and recognition, and more specifically those related to human face, has greatly increased their demand in recent
