Abstract

Shape is one of the salient features of visual content and can be used in visual information retrieval. Radius vector function for star-shaped objects is available. A modified radius-vector function for both types of shapes-star shaped, and non-star shaped is presented. The center of gravity is selected as the reference point, while the principal of axes is selected as the reference line. The corner points are marked as the nodes. Normalized distances are stored from the reference point to the corner nodes. The Euclidean distance of the center to the corner distances of test object with those of objects in the database is used for shape matching.
