In the paper combined calculation of multiple COG algorithms for different window sizes in parallel is considered. It is possible to process 2D data together instead separate calculation of COG for every window size. Proposed technique uses typical abilities of horizontal and vertical processing available in modem processing devices. Selection of the index values used in the COG is considered and applied to the calculation. COG algorithm support subpixel estimation of the position for small object. Such algorithm could be used for efficient implementation of detection and estimation systems for the large sets of object.
