Mina's profile - activity

I have used meanshift function of opencv for face tracking. The subject is working with the computer and I have initial face region of him by some other method so I have very good training template for creating my histogram.I have used both both h and s channels in creating the histogram

The problem is that the tracking window sometimes goes on the background because the subject's skin tone is similar to the wall color.

Any comments pleas,

Thank you.
