ResumoIn the companion paper [7] a grouping strategy with a firm geometrical underpinning and without the problem of combinatorias is proposed. It is based on the exploitation of structures that remain fixed under the transformations that relate corresponding contour segments in regular patterns. In this paper we present a solution for the complementary task of extracting these fixed structures in an efficient and non-combinatorial way, based on the iterated application of the Hough transform. Apart from grouping, this 'Cascaded Hough Transform' or CHT for short can also be used for the detection of straight lines, vanishing points and vanishing lines.
