以前的数字图像处理作业，包括直方图，均衡，Sobel，中值，FFT,IFFT,DCT,IDCT,8*8DCT等-previous digital image processing operations, including the histogram, balanced and Sobel, values, FFT, IFFT, DCT, IDCT, 8 * 8DCT etc.

使用matlab在数字图像处理中画直方图,放大，缩小图像等的小程序-using matlab to draw histogram,zoom in or zoom out in DIP

实现了DIP得一些基本功能,如直方图，锐化，增强，DFT,IDFT等。-it contains some basic methods of DIP
