To speed up an algorithm remember that every memory access takes time. try and have your data in small arrays for instance remember the 3 elements in every line of the square in an array, now when you want to calculate add the last number and substract the first one. this way you use 2 memory accesses instead of 3. it is even faster because normaly the array is stored in the cash and th e image is not.
in essence avoid as much as posible reading the image and use short memory segments
