The technology of face recognition in the past few years obtained the very big development, but due to the face of nonrigid, expression and changeablefactors, the face recognition technology in practical application are facing great difficulties. This paper aimed at home and abroad in recent years the relevant papers and researchreports on study and on the basis of the analysis, some units within the data sensitivity places need to enter personnel to carry out limitation design and develop a set of identity verification identification system, the system uses PCA face recognition method, therealization is simple and the accuracy rate of recognition is high,but itsdrawback is that a large amount of calculation, when to identify more staff,this method is difficult to do. The realization of a set of various pretreatment methods in one of the generic face image preprocessing simulation system based on MATLAB, the system is used as the image preprocessing module can be embedded in a face recognition system, and using the histogram matching gray image to realize the recognition of human face images to determine.
