Kokul Hi Aleksey,

Although, fps of the youtube video could be better. You can download overlapped_sonicfire.avi to see original video. If you have any particular question, you are welcome. Aleksey Hi Kokul,

The algorithm is specially optimized for real-time performance. Nikkey,

Have you done anything special works to remove the shadows? Thanks Kokul Hi,

You have removed the moving shadows accurately. Have you done anything special works to remove the shadows?

Thanks

I have to know, is it possible to do those things in real time. Wont it take much time? In my point of view "Running Gaussian Average" will take some time.

They might have gone out of the camera view especially if you are dealing with occlusions towards edge of view. At the time of occlusion, how can you say certainly that blobs merged ?
