IMAGE PREPROCESSING BASED ON SINGULAR VAILUE AND FACE RECOGNITION

In order to enhance the classification information of a image, we use band-pass filtering to preprocess face image and to improve the sort performance of singular value feature. We give a group of circular filter functions, use genetic algorithm to select the frequency band of larger divisibility value, and design the expression of chromosome and the solution of fitness. Experiments prove that we can get better sort result of singular value feature by doing preprocessing than undoing it.
