I am tracking a human using centroid. But in case of tracking human overlap to other human(occlusion) or stationary for a while the bounded box and centroid shift to undesired other human. I am New at matlab. Please help me out.

Handling occlusion in tracking is a difficult problem. You could make some progress with a Kalman filter, but be advised that something as simple as centroid has limitations and you can't expect it to work in anything but the simplest cases. You could possibly have more stable results if you track the head... As long as they are not dancers! A better solution of course is to track all the humans in the scene. You will have less chance of losing/switching subjects and you can post-process to remove noise from occlusions.
