By using a high resolution image but using a mask we keep the accuracy white the mask improves the speed.
As for location of the target, that isnt a problem.

Interesting... We don't have accuracy issues with 320x240. What kind of inaccuracy are you seeing? Too many false positive particles? In any case, I suspect if you tune the filters correctly, you will increase your accuracy. This may be easier than trying to crop the image.
