其中dft.m 是通过该程序同时输出图片1,2的R、G、B三通道的DFT正反变换图、相角图、幅度图，图片1,2的彩色DFT正反变换图以及DFT后图片1,2幅度相位信息置换后的彩色结果图。



dct.m是通过该程序显示“实验室用原图像”中的图片3的R、G、B三通道DCT正反变化对比图，变换系数图以及彩色DCT正反变换图。



compress.m是通过该程序输出图片3的保留n个DCT变换系数重构彩色结果图。需要说明的是其中决定保留系数个数n的mask矩阵需要手动更改。-Wherein the DFT transform pros FIG dft.m output simultaneously through the program picture 1,2 R, G, B three-channel, phase angle diagram, amplitude, picture 1,2 color map and DFT DFT transform pros after the results in Fig. 1 and 2 color image amplitude and phase information after replacement.



dct.m by the program shows　laboratories original image　in the Picture 3 of R, G, B three-channel DCT positive and negative change chart, conversion coefficient map and a color diagram DCT transform pros.



compress.m through the program output Picture retention of n DCT transform coefficients reconstructed color results in Fig. It should be noted that where the decision to retain the mask matrix coefficients n the need to manually change the number.
