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.
