Definition
Shape is an important image feature, it is the geometrical information of an object after removing position, scale and rotational effects [3]. A shape is often represented by the contour map extracted from the images. Given a query 2D shape, 2D shape retrieval retrieves a ranked list of similar 2D shapes from a collection of 2D polygonal models (contour points) based on the shape characteristics.
(Fig. 1) gives an example object shapes, which are represented by the extracted contour maps.
