We also need to provide initial location of window.

WebMean Shift Tracking Mean shift is a non-parametric feature-space analysis technique, a so-called mode seeking algorithm. It is a procedure for locating the maxima of a density function given discrete data sampled from that function. In a sense, it is using a non-parametric density gradient estimation.
