Hi,
I am new to matlab and image processing.
For better undestanding of DFT and DCT operation on a RBG image, please provide some sample codes.
Code for plotting the the frequency components of an image would be an added help for me.
Thanks in advance.

hi,
Directly we cant apply DCT in a color image.First we converted that into gray and perform the dct operations.otherwise separate RGB planes then apply DCT/IDCT for each plane. Finally just combine all the planes.You will get better result.
