This article proposed and has realized one kind based on thedifference picture person face examination algorithm. This algorithmcarries on two values pictures processing in the differencefoundation, according to the human body statistical characteristic,proposed through the judgement projection curve second time derivativesize, determines the person face boundary the method. This algorithmmerit is may delete the background picture in with the person faceimage same fixed region, not only can effectively restrain thebackground noise, reduces by mistake examining rate, moreover also canreduce the person face examination scope, speeds up the examinationspeed. The experiment indicated that, this algorithm feasible, iseffective.
