Your chances of getting help would be much higher if you could isolate your problem: Find the line or lines (2-3 lines, not 20 lines) that take most of the time, and post some code that can be benchmarked with e.g. a random matrix. (That would also make potential answers more usable to other people.) And really: if you want to improve performance, finding out where the bottleneck is should be your first step anyway.

This would be easier if you would post a few images...

Sounds like [en.wikipedia.org/wiki/Background_subtraction], but I don't think MMA has a built-in function for that.

@mrz: You would simply use DiskMatrix instead of BoxMatrix

@Guesswhoitis. I wanted to make the step from Count[data, {0., 0., 0.}, Infinity] to Norm[# - {0,0,0}] more obvious.

Why don't you process the source image (before the Colorize step) - wouldn't that make the counting easier?

comment How to put an imported image in a Disk?
@LightnessRacesinOrbit: Easier said than done. The OP mentioned a face, and of the 6 portrait images in MMA's ExampleData collection, all are female, and at least 3 of them look suspiciously like pin-ups.
