Detailed Description

This is an implementation of the tracking algorithm proposed by Hieu T.

Nguyen and Arnold Smeulders in the paper "Tracking aspects of the foreground against the background".

Todo:

add parameters (such as sigma, number of orientations) to constructor (perhaps in struct)

Please note that for speed considerations a search area of 21x21 is used. It might be possible to use the abstraction SearcherBase, so that the foreground/background tracker can be used with other seatch strategies.
