With the rapid development of science and technology, the safety factor of traditional identification such as access cards, identity cards, passwords, etc. is relatively low, and which are easy to be cracked. However biometric identification makes identity authentication more reliable, and can reach the safety factor expected. In order to solve the problems above, this paper presents a common face recognition algorithm and improves the algorithm, and then do comparison experiments on the recognition rate between the common algorithm and the improved algorithm based on the ORL face database. Finally the results are validated by the graphical user interface on Matlab.
