The following Matlab project contains the source code and Matlab examples used for 2 d dct idct for jpeg compression.
to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression
for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution
now compare our special 8X8 functions with the internal general functions
use this code:
A = int32(100*rand(8,8));
tic;for i = 1 : 1000 IDCT_8X8(DCT_8X8(A));end;toc;
tic;for i = 1 : 1000 idct2(dct2(A));end;toc;
