Shape retrieval using triangle-area representation and dynamic space warping
We present a shape representation and a matching method for nonrigid shapes with closed contours. The representation utilizes the areas of the triangles formed by the boundary poi...

Cost-based closed-contour representations
This paper presents an efficient technique for linking edge points in order to generate a closed-contour representation. It is based on the consecutive use of global and local sch...

ANSIG - An analytic signature for permutation-invariant two-dimensional shape representation
Many applications require a computer representation of 2D shape, usually described by a set of 2D points. The challenge of this representation is that it must not only capture the...

Graph extraction from color images
Abstract. An approach to symbolic contour extraction will be described that consists of three stages: enhancement, detection, and extraction of edges and corners. Edges and corners...
