ChessTracker

class ChessTracker extends Tracker

The ChessTracker class is used for image tracking algorithms based on the idea of minimizing the difference between a sub-image of 'a' and a subsequent displaced sub-image of 'b'. This algorithm searches for improvements in displacement 'd' in multiple directions and with multiple iterations. It may be viewed as a form of Generating Set Search (GSS).
