-http://en.wikipedia.org/wiki/Mean-shift
-In this application the idea, is to eliminate any bias of the point estimate 
-which is introduced by the rather arbitrary thresholded area. One must recognize
-that the thresholded area can only move in one pixel increments since it is
-binary. Thus, its center of mass might make "jumps" as pixels are added/removed
-from the thresholded area.
-With mean-shift, a moving "window" or kernel is multiplied with the gray-scale
-image, and the COM is calculated of the result. This is iterated where the
-kernel center is set the previously computed COM. Thus, peaks in the image intensity
-distribution "pull" the kernel towards themselves. Eventually it stops moving, i.e.
-then the computed COM coincides with the kernel center. We hope that the 
-corresponding location is a good candidate for the extracted point.
-The idea similar to the window scaling suggested in  Berglund et al. "Fast, bias-free 
-algorithm for tracking single particles with variable size and shape." (2008).
