How? You do it. Whats the problem? All that matters is what you will do with it, and only you know that.

Like John said, it depends on what you will do with it - how you will use it. If you want to make a histogram, you need to find out what block you're in
for col = 1 : cols
for row = 1 : rows
% Get the RGB values of the image.
rValue = rgbImage(row, col, 1);
gValue = rgbImage(row, col, 2);
bValue = rgbImage(row, col, 3);
% Find out which of the 64 blocks they belong to.
% Block numbers range from 1 to 4.
rBlock = ceil(rValue / 64);
gBlock = ceil(gValue / 64);
bBlock = ceil(bValue / 64);
% Increment the histogram.
rgbHist(rBlock, gBlock, bBlock) = rgbHist(rBlock, gBlock, bBlock) + 1;
end
end
