Abstract
The problem of obtaining intuitive descriptions of planar shapes
is addressed. In particular, a method for producing a segmented axial
description of a given shape together with a hierarchical decomposition
of the shape into its parts is suggested. Smooth local symmetries are
used for the axial description of parts. Parallel symmetries are used to
provide information on global relationships within the shape. It is
assumed that the shape is a closed planar curve. The approach uses both
region and contour information, can handle shapes with corners, and
addresses the issues of local versus global information, the issue of
scale and the notion of part. The method is computationally efficient,
robust, and stable. Results showing that it provides an intuitive shape
description are presented
