Recognition of Shapes by Editing Shock Graphs Appears in ICCV 2001, pages 755-762 (2008)
Thomas B. Sebastian, Philip N. Klein, Benjamin B. Kimia
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...
SEBASTIAN et al.: ON ALIGNING CURVES 1 On Aligning Curves (2008)
Thomas B. Sebastian, Philip N. Klein, Benjamin B. Kimia
Abstract — We present a novel approach to finding a correspondence (alignment) between two curves. The correspondence is based on a notion of an alignment curve which treats both curves...
Perceptual Organization as Object Recognition Divided by Two 1 Background (2008)
Marc Johannes, Thomas B. Sebastian, Huseyin Tek, Benjamin B. Kimia
Perceptual grouping is the organization of visual elements into groups which depict an increased level of regularity. Gestalt psychologists posited that visual elements should be grouped based on...
1 Division of Engineering, (2007)
Thomas B. Sebastian, Philip N. Klein, Benjamin B. Kimia
Abstract. This paper examines issues arising in applying a previously developed edit-distance shock graph matching technique to indexing into large shape databases. This approach compares the shock...

Alignment-based recognition of shape outlines (2001)
Thomas B. Sebastian, Philip N. Klein, Benjamin B. Kimia
We present a 2D shape recognition and classication 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...
Shape matching using edit-distance: an implementation (2001)
Philip N. Klein, Thomas B. Sebastian, Benjamin B. Kimia
We report on our experience with the implementation of an algorithm for comparing shapes by computing the editdistance between their medial axes. A shape-comparison method that is robust to various...
Curves vs skeletons in object recognition (2001)
Thomas B. Sebastian, Benjamin B. Kimia
The type of representation used in describing shape can have a significant impact on the effectiveness of a recognition strategy. Shape has been represented by its bounding curve as well as by the...
