Difference Picture Based Face Detection And Tracking

Research efforts in face processing include face detection, face tracking, face recognition and expression analysis. The face detection and tracking is key technology of the field efface information processing. It's widely applied in the fields of automated face recognition system, based on content index, video monitoring and human-machine alternative technology.In this paper several research works are given as follows: First the methods of image segmentation are summarized and analyzed. An algorithm of image segmentation is developed based on self-adaptive threshold value. With the difference algorithm of image sequence, I can eliminate the background and extrude the moving object in images. Then hair clustering analysis, face geometry character are applied to verify very candidate region to get real face regions. The detected face is used as matching template in face tracking. Second thefour general ideas of face tracking are pondered upon and analyzed and generate algorithm has a good application in optimization process. An algorithm of face tracking with generate algorithms is developed. In order to reduce the computation, a new method of selection initial population has been presented. Finally face real-time capture, face detection and tracking have been realized by video camera made in Ningbo mingjong company. The video camera is connected to computer by USB.In this paper, PCCamera M6215 grabbed the tracked images and all algorithms were accomplished by VC++ in Windows2000 environment.
