Splitting an image into smaller regions

Hi Guys,
I'm working on a code that creates an RGB descriptor for visual search. i've managed to implement the rgb descriptor on the whole image. but i wanted to experiment by splitting the same image up into smaller areas and rerun the experiment by calculating the rgb descriptor on smaller parts of the image.
the reason behind this, is because i'm using a query image against a dataset in order to find visually similar results. but if i split up my image into smaller pieces, i got a feeling it will be more accurate.
my question is, is there a function or piece of code that could help me with this?
Thanks

So you have 2x4 = 8 total histograms, and you want to sum all the bins to get the histogram of the complete array? Well, if so, that would simply be the histogram of the entire, complete image. Why should it be any different??? Then if you sum that histogram, it's simply the sum of all pixel values. Again, why do you expect anything different?
