Hi.
I'm facing the same problem with the background subtraction.
I have a stable camera recording at 60fps an animal walking in the sagittal 
plane in a indoor area. I'm lighting the area using a few tungsten lamp (working 
at 60Hz). Despite that, analyzing the frames one by one I can still notice very 
small changes of the bright (flickering). Is that normal?

Beside that, I used an algorithm for the background subtraction found at http://staff.science.uva.nl/~zivkovic/DOWNLOAD.html 
It's working quite well but I still have problems with the extraction of a leg of 
the animal (that has, more or less, the same color of the background). Anyone 
can suggest me what I can do to improve the extraction of the animal?

By the way, for every video I have to set different parameters to make the 
algorithm working well. But I would like to avoid that in order to use it in semi-
real time application.
