Face Detection Based on Cascade Support Vector Machine QIU Xiaojia ZHAO Xiuying WANG Jikui (Luoyang College Of Technology, Luoyang 471003, Henan) Abstract:An efficient method of face detection based on cascade Support Vector Machine (CSVM)is proposed in this paper. Firstly,a LSVM coarse filter with relatively lower computational complexity is applied to the whole input image to filter out most of the non-face, then follows the NOSVM classifier to make the final decision,so the detection process is speeded up. The experiment results show that the method can effectively detect faces under complicated background,and the processing time is shorter than using SVM alone.
