Abstract: Visual object detection has conceivably prevailing applications in the Internet age for multimedia interactions. This thesis aims to explore the data-parallel architecture of commodity graphic processors that enables fast and promising object detection. Firstly, Boosting is identified as the promising and widely usable approach for object detection. An efficient architecture in streaming paradigm is then designed to map the boosted cascade to GPU as data streaming coprocessor. We take into ccount the hardware characteristics to enable further speedup. Promising results were achieved, as up to 5 times speedup was obtained. By study the performance impacts from experiments on GPUs that are of different generations, we explore the suitable designs for future generation GPU models. Our experiences reveal the underlying principles when mapping the boosted detector to similar data-parallel architectures.
