Hi!
I have a few problems with the background subtraction. I hope somebody
can give me any hints.
1)I have a stable camera recording at 60fps an animal walking in the
sagittal plane in a indoor area (the background is always the same).
I'm lighting the area using a few tungsten lamps (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?
2)I use an algorithm for the background subtraction found at
http://staff.science.uva.nl/~zivkovic/DOWNLOAD.html
It's working quite well (I almost get the perfect shape of the animal)
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 algorithm? Especially for the
parts that are similar to the background..
3) for every video I have to set different parameters to make the
algorithm working well (due to light changes). But I would like to
avoid that in order to use it in semi-real time application.
I even tried to calculate the mean of the background (~50 frames) and
then subtract it to every frame but no good results.
Thanks in advance!
