I need to select an 8 pixel by 8 pixel region of the image from an interesting area of the image and perform 2D DCT on it.

Hi,
You can use the imcrop() function to crop the region of interest an image, and perform 2-D DCT using dct2() function. Alternately, you may also select the region of interest by specifying the rows and columns parameters of the dct2() function.
