MATLAB: Dividing image into 64 blocks

image processing

I have an image ,i want to divide it into 64(8×8),blocks,please help

I - your image

[m n k] = size(I)
outIblocks = mat2cell(I,m/8*ones(8,1),n/8*ones(8,1),k)

reshape(a,[],32,16)

aux_fun = @(block_info) YourFunction(block_info.block);
result = blockproc(aux_fun, [64 64], 'TrimBorder', false);

YourFunction should take in a 64 x 64 block and return the ratio or a vector of information.

Note: more work is needed if the image is not an exact multiple of 64 on each side.
