Abstract
This paper shows, in an introductory manner, how Hough Transform can provide a versatile approach to many questions concerning planar convex shapes, with a special attention paid to origin changes. Applications are given in the domains of shape symmetry parameters and length computation. Radon Transform is shown to be a natural extension of Hough Transform to gray-level and/or non convex shapes.
Keywords : convexity, Hough transform, image processing, Radon transform, shape parameters, shapes, support functions
