Description

Hello there.
In terms of a parallel programming course in my master degree, I have implemented a parallel version of plImage to cvHistogram conversion and comparison.
The speedup I achieved is 6x when you add 8 cpus... This means that if you have 8 cpus it gets 6 times faster to convert two images from plImage* to cvHistogram* and compare them using cvCompareHist() rather than having just one cpu.
I can submit you the source code with more details if you find that interesting.

Many thanks,
Dimos.

Could you provide your code? What parallel framework do you use (OpenMP, TBB, pthreads, WinThreads)?
