Camera Software System Based On Face Recognition Algorithm Of Feature Points

Face detection and face tracking technology is very popular now. It has a widely applications in security , finance , judicature and network transmission. At the present time , it has been recognized with the research studiers more and more important. Further more, people are not only satisfy with the application in these important ways, but also they want use this useful technology in PC camera.There are four familiar method about face tracking . They are : based on model , based on the information of locomotion , based on the face feature and based on nerve network. . As one part of the method based on model , the method based on skin model has high veracity and can be good realized. So it has a widely use in the domain of face tracking.In this text, at the first combine the study result of inland and overseas scholars , deeply analysed the base theory of face detection and feature detection. Then put forward a optimized arithmetic of face detection and tracking which is based on skin model, and the arithmetic of feature detection which is based on the information with Sobel , Chrominace, and Luminance . At the last , This text have finished the interesting software system with Microsoft Directshow kit. And apply the software system in a PC camera production. By passing the test, these arithmetic and software have a good effect in detective and tracking . And its adaptability is also very good.The method in this text , will satisfy the wish of people want to use the popular technology. With the PC camera production , this software system has big market value.
