Shape Representation by Multiscale Contour Approximation

Abstract

We present an approach for deriving qualitative descriptions of contours containing structures at different (unknown) scales. The descriptions are in terms of straight a m , curved arcs with sign of curvature, corners, and points delimiting the arcs: inflexion points and transitions from straight to curved. Furthermore, the tangents at these points are… (More)
