Visão computacional
Abstract in Portuguese
Esta tese apresenta um estudo sobre a implementação de sistema de detecção e reconhecimento de faces no processador CELL na plataforma CBE, utilizando um sistema Playstation 3. Inicialmente, diversas abordagens para reconhecimento e detecção de faces são estudadas, bem como arquiteturas de processador multi núcleos. São apresentadas três implementação, sendo a segunda implementação premiada com quarto colocado no IBM CELL UNIVERSITY CHALLENGE 2007 para desenvolvimento de programas para plataforma Cell BE. A terceira implementação apresenta os resultados interessantes relacionados a vetorização do processamento dos dados da detecção de objetos e os recursos adotados para obter o melhor desempenho.

Abstract in English
This thesis presents a study of face detection implementation on CBE plataform and employ the system with Playstation 3 hardware. Several approaches for face detection and recognition are studied as well as multicore processor architetures. We implemented three versions of system. First implementation was a naive reference implementation with worst performance. Second implementation granted fourth prize in IBM CELL UNIVERSITY CHALLENGE 2007 that incentive development on CBE plataform. Third implementation had most interesting results with vectorized approaches on code of object detection.
