Question:
The problem with thresholding the DCT coefficients of an image to compress it, is that the locations of the chosen coefficients are arbitrary and difficult to code. Consider then using a mask W(k, ℓ)
of the same dimension as the DCT array fCx(k, ℓ)g. Now the location of the chosen DCT coefficients is known. Consider the cameraman image, compute its DCT coefficients that form a matrix Cx and let
Ĉx = WCx
be the DCT coefficients of a compressed image. Show the original and the compressed images, and the supports of the original and the masked DCT coefficients.
