Fast and precise angular projection evaluation (Hough-Green transform)
Vladimir A. Shapiro · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2004
The novel approach to angular projection calculation on discrete binary images, regarded to as the Hough-Green Transform (HGT), based on tracing object contours is introduced. This approach is usually much more computationally effective than the conventional Standard HT (SHT) on objects with a lot of interior pixels, as the acceleration factor is proportional to area by circumference ratio. The HGT is also more accurate than the SHT.
