Brute Force Histograms

I have improved a worked out the few obvious bugs with my former "histograms". Now as you can clearly see they are much more correct, and i have also altered my code to allow overlapping windows but they must differ by a window size of at least 1/4 this can be altered but i think for a start it is a good heuristic. It gives a decent coverage however the random generator doesn't seem to like the corners very much, i am not sure why as when i tested this at the start it gave me a variety of numbers from the minimum allowed to the maximum in the range, so i would expect them now maybe its simply a bad case?

The chi squared results though are lower than i had hoped, as you can see from these results they do not have a particular one which shines out as having or containing any useful information in fact the value is quite low and the margins not overly noticeable.

Chi Squared for sample image, larger values bolded.
