| Abstract: | According to face detection for videos,a fast detection algorithm based on regional features was proposed in the paper.The comprehensive algorithm with temporal difference and background difference was used for acquiring and tracking the moving objects,which can avoid updating error of background model caused by moving object.In the region of moving objects,first Trisection image model of mosaic based on regional feature was used for detecting face region,then the frequency histogram method was adopted to c... |
