窗函数设计高通，低通，带通滤波器。课程实验设计(Window function design high-pass, low pass, band pass filter. Experimental design courses)

This code calculate the PSNR between the original and the distored image, and give the value of this PSNR.

MATLAB计算机视觉与深度学习实战-运行视频(As a biological technology, face is difficult to be stolen and infection-free. In addition to that, it enjoys the authentication concealment and is never forgotten. Therefore, authentication based on face recognition will become the mainstream of future development. It has important and extensive application in various fields, and is also a hot topic at present biological characteristics identification technology research. Under the non-restrictive condition, the face recognition rate is not high, and its accuracy needs to be further improved. In this paper, the following aspects is analyzed)
