u will have to convert the image into Y, Cb, Cr. this is luminanace and
chrominance, which cna be derived from the RGB using a Matlab function RGB2YCBCR
given in the MATLAB help. Again at decoder once the inverse DCT is applied you
can use MATLAB function YCBCR2RGB.
I am doing a project in image processing.in this i have to apply dct to rgb
image and encode it using turbo codes.after decoding i have to retrieve my
original rgb image by applying idct.anyone know this using matlab coding
