The target tracking is an important part of many applications. There are a lot of algorithms for target tracking but I wouldn't consider them. For those who are interested in algorithms I proposed to visit the site. My contribution in target tracking algorithms is optimal thresholding. Suppose that an image contains only two principal brightness regions. The histogram of such an image may be considered is the sum or mixture of two functions, one for the light and one for the dark regions in the image (Gonzales, Woods, Digital Image Processing). In general, analytically determining parameters that split histogram in these two functions is not a simple matter. I realized fast algorithm for such splitting.

You can download the Matlab code for testing.
I'll appreciate any feedback and examples of bad results of suggested algorithm.
Source code for my binaries can be obtained for research purposes. Please contact me for details.
