| Alignment-Based Recognition of Shape Outlines (2001) | |||||||||||||||||
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 e#cient 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 e#ectiveness of the recognition system on a variety of examples. | |||||||||||||||||
