WebbThis filter uses a histogram matching technique where the histograms of the two images are matched only at a specified number of quantile values.\n\nThe filter was originally … WebbAbstract. We propose a novel method for template matching named THTM – a template matching algorithm based on HOG (histogram of gradient) and two-stage matching. We rely on the fast construction of HOG and the two-stage matching that jointly lead to a high accuracy approach for matching. TMTM give enough attention on HOG and creatively … leading at a distance
