Recently, the novel approach to Hough Transform (HT) calculation, regarded to as the Hough-Green Transform (HGT), was proposed. This approach is based on tracing object contours on bitonal imagery; therefore it is usually much more computationally effective than the Standard HT (SHT) on objects with a large number of interior pixels, as the acceleration is proportional to area by circumference
