对图像进行YCbCr分解
- rgb=imread('lena.png'); YCbCr=rgb2ycbcr(rgb); subplot(221),imshow(rgb),title('image'); Y=YCbCr(:,:,1); Cb=YCbCr(:,:,2); Cr=YCbCr(:,:,3); ycbcrmap(:,:,1)=Y; ycbcrmap(:,:,2)=128; ycbcrmap(:,:,3)=128; subplot(222),imshow(Y),title('Y'); ycbcrma
RGB2YCbCr(0-255)
- This module converts the incoming Red, Green, and Blue 8-bit pixel data into Y, Cb, and Cr 8-bit values. The output values will be unsigned in the range of 0 to 255. data_in contains the Red pixel value in bits [7:0], Green in bits [15:8], a

CompressionbyYikwang
- This code perform the DCT and quantization on all the channels without any sub-sampling and for the compression of color images, they are first converted to the YCbCr color format and vice versa, use the function rgb2ycbcr and ycbcr2rgb.
