This article put forward and realized one kind of measure method based on the difference image human face examination algorithm.This algorithm carries on two value imagery processing in the difference foundation, according to the human body statistical characteristic, proposed through the judgment projection curve second time derivative size, determines the human face boundary the method.This algorithm merit is may delete the background image in with the human face image same fixed region, not only can restrain the background noise effectively, reduces examines by mistake rate, moreover also can reduce the human face examination scope, speeds up the examination speed.The experiment indicated that, this algorithm is feasible, is effective.
