Alignment-based  Recognition  of Shape Outlines

Abstract

We present a 2D shape  recognition and classification method based on
matching  shape outlines. The correspondence between outlines  (curves)
is based on a notion of an alignment curve and on a measure of
similarity between the intrinsic properties of the curve, namely, length
and curvature, and is found  by an efficient dynamic-programming method.
The correspondence is used to find a similarity measure which is used
in a recognition system.  We explore the strengths and weaknesses of
the outline-based representation by examining the effectiveness of the
recognition system on  a variety of examples.
