English Description：
Face image detection is to extract face image in the case of complex background. Face image recognition is to compare the extracted face image with the image in the standard database, recognize and display the results. In this paper, skin color (i.e. brightness component, blue chromaticity component and red chromaticity component) model is used to detect human face, and principal component analysis (PCA) algorithm is used to recognize human face.
