Description: 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.
