how to find lowest vertical and horizontal DCT coefficient of an image block

I have an image of size 256x256 and it is divided into equal non overlapping blocks of size 8x8. I have to find the lowest vertical and horizontal DCT (Discrete Cosine Transform)coefficients of each image block. Is there any method available for this problem in MATLAB?
