On the computation of the affine skeletons of planar curves and the detection of skew symmetry

Journal Article

In this paper we discuss a new approach to compute discrete skeletons of planar shapes which is based on affine distances, being therefore affine invariant. The method works with generic curves that may contain concave sections, A dynamical interpretation of the affine skeleton construction, based on curve evolution, is discussed as well. We propose an efficient implementation of the method and give examples. We also demonstrate how to use this method to detect affine skew symmetry in real images. © 2001 Pattern Recognition Society.
