English Description：
This project presents a face detection technique mainly based on the color segmentation, image segmentation and template matching methods.Detection of skin color in color images is a very popular and useful technique for face detection. this project used YCbCr components since it is one of existing Matlab functions thus would save the computation time. In the YCbCr color space, the luminance information is contained in Y component; and, the chrominance information is in Cb and Cr. The nest step image segmentation process consists of three steps. The first step is to fill up black isolated holes and to
