I implemented the camshift algorithm to detect an object but I am not happy with the output.

I used hue channel in HSV color space to generate the histogram.

Now i want to embed kalman filter with camshift. But I have no idea of doing it. Need guidance.

Why do you want Kalman if you have no idea what to do? It would be good to first understand what are you doing there, then learn about Kalman, then decide whether it is useful in your situation.

As a note to Sammy's comment. Please define whether you actually want to perform detection or tracking. I think you are mixing the two up. Camshift is not a detection, but a tracking algorithm (http://www.robinhewitt.com/research/track/camshift.html). So state clearly what the mean of your research is...

hi, actually i want to track the hand..i want to do something like this http://www.youtube.com/watch?v=dhYwCmKGU3w So how can i join Camshift and Kalman algorith together to track an object ?

I guess you did not read my comment correctly. The video show a manual selection of a region, which could be your hand, then you apply tracking of that region based on that regions information. Just use a Kalman filter and read about how it actually works. This is not a "hello provide me a full solution forum" :)
