Research output: Contribution to journalArticlepeer-review


We present an approach for automaticaly finding corresponding points between two perspective views (images) of a moving polyhedron when the two imges exhibit consid­erable perspective shape distortions. The approach consists of two phases. In the first phase a heuristic search process is used to extract two line drawings (graphs) from the gray level images, and in the second phase a relexation process is used to get a reliable matching between the two drawings.
