This paper presents a novel recognition framework which is based on matching shock graphs of 2D shape outlines, where the distance between two shapes is defined to be the cost of the least action...
Alignment-Based Recognition of Shape Outlines (2001)
Thomas Sebastian Philip, Thomas B. Sebastian, Philip N. Klein, Benjamin B. Kimia
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...
