Another thing would be to rearrange the loops so the outer one executes
less times; if you know that borderXsizeX and borderYsizeY

Can I then simply ignore the time data then? I do see better performance
obviously the smaller the box is, but I guess my issues is how seriously to

The project I'm working on is motion detection, involving a bit of image
processing. No worries: no image processing background needed.
Suffice to say that I initially wrote a script that goes through every pixel
