Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

人脸识别的经典算法——直接LDA算法的matlab实现，效果很好，还可以计算识别的精确度，实现了剑桥大学orl人脸数据库的人脸识别(The classical LDA algorithm directly face recognition algorithm matlab implementation, the effect is very good, also can calculate the recognition accuracy, the realization of the University of Cambridge ORL face for face recognition)
