N2 - An adaptive high precision image object centroid - center of mass (COM) detection system employing a 2-D dynamic element matching (DEM) algorithm for object tracking is presented. This proposed system outputs a high resolution COM location of the most salient object in the field of view for tracking and navigation purposes and is suitable for real time applications. Pre-computation object detection is performed by a low resolution mixed signal winner-take-all (WTA) circuit. In this work, the COM computation algorithm parameters are adaptively changed according to the object size, enabling lowering object scanning frequency, but still providing a high precision in the object COM location. Simulation results prove the concept and demonstrate the high precision COM detection result. In addition, a possible hardware implementation is described.
