Abstract：
 The present invention belongs to the field of image processing, computer vision and pattern identification technology, including: positioning human face image; extracting five kinds of human face components of bare face, eyebrow + eye, eye, apax of nose and mouth from whole human face; and extracting five human face components from human face image of every one of training set, from human image of known every one and from human face image of every one to be identified, utilizing characteristic face method in principal component analysis to respectively form five characteristic components and projected characteristic values of five human face components of known human face and creating data base including projected characteristic values of five human face components of known human face and compressed image of known human face and personal identity archive of known person and projected characteristic values of five components of human face to be identified, and adopting computer similarity and sorting method in similarity to make multi-mode whole face and local face identification. It can obtain high identification rate.
