I do in using opencv image matching CV_TM_SQDIFF_NORMED with standard (yi - (mxi + b)) matching with the head of a person to match, if have the head of the person in the image matching is no problem,, but I don't have the pictures as the picture inside when he can give me disorderly matching one, and then use minMaxLoc minVal is 0, then the problem come to pick it up I don't how to judge the image inside the head? I use the online example of yao's head

CvMinMaxLoc, look back very much, also is the similarity, similarity of low matching can count as a failure
