My goal is only to achieve near real-time performance :)
The  'homogenous' definition, for my application, is the simplest :
(abs(grayLevelDifference) < threshold).
What do you think about "split and merge method" and "single pass
split and merge method"? The first seems to be time consuming, while
I've not understood well the second.  You can find a brief description
of the algorithms here:
