Hi all,

I need to separate the background from the foreground in a video using Kalman filter. Can somebody give me some resources or examples to follow.

Thanks.

The foregroundDetection is not working , it shows only a ball traversing a Box but i cannot see any foreground extraction ! , the same thing if i tried with another video. Can you help on that , thanks.

Then call them and tell them that their posted demo does not work at all. I'm sure they would want to know.

This is not an answer to chfakht's original question. You should start your own question for this, if, after running my Image Processing Tutorial in my File Exchange you still can't figure it out. If so, read this and post your image and tell us what the foreground and background are, and tell us what "separate" means to you (like do you want a logical mask, a masked gray scale image, or what????). Also, tell us what you want to measure once you have segmented out the foreground and background.
