| Abstract: | To meet the requirement of the multi-view face detection in the field of embedded system,this paper first implements Real Adaboost algorithm on the DSP platform(TMS320DM642).To improve performance,algorithm level and implementation level optimization are introduced and result in a processing speed of 18 frames per second.The experimental results show that compared with the system based on Discrete Adaboost algorithm,the system is more adapt to multi-view face detection.It enlarges the application scope of t... |
