if true
I = binary_image;
numBlkH = 8;
numBlkW = 8;
[imgH,imgW,~] = size(I);
szBlkH = [repmat(fix(imgH/numBlkH),1,numBlkH-1) imgH-fix(imgH/numBlkH)*(numBlkH-1)];
szBlkW = [repmat(fix(imgW/numBlkW),1,numBlkW-1) imgW-fix(imgW/numBlkW)*(numBlkW-1)];
C = mat2cell(I, szBlkH, szBlkW)';
C = C(:);
figure,
imshow(I)
for i=1:numBlkH*numBlkW
subplot(numBlkH,numBlkW,i), imshow( C{i} )
end
end
