Hi, You should have just continued the post that you started here:
http://www.mathworks.com/matlabcentral/answers/49323-how-to-apply-8x8-dct-on-a-image
Did you read the help for dct2() and blockproc()?
fun = @(block_struct) dct2(block_struct.data);
RGB = imread('autumn.tif');
I = rgb2gray(RGB);
Y = blockproc(I,[8 8],fun);
