Method of sampling color of image of video sequence and its application to color clustering

摘要

The method comprises the steps of, successively for each image (2) following a preceding image (1), - based on a map of motion vectors that corresponds to the motion from said preceding image (1) toward said following image (2), building a pixel mask for said following image (2), - applying said pixel mask to the corresponding following image (2) in order to obtain a corresponding masked image that samples the pixels of said following image (2). The application of this method to color clustering allows the iterative update of the colors clusters with limited computer resources.
