u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A

. Write MATLAB code that will do the following. (a) Apply DCT on an image and obtain the o/p (b) On the DCT image apply quantization using standard quantiser. (8×8) (c) Apply IDCT to retain back the image. Apply Hoffman compression -. Writ
