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. The corner points are marked as the nodes. Normalized vectors are calculated from the reference point to the corner nodes. The normalized vectors are arranged in ascending order, and the Euclidean distance of the query object with database objects is used for shape matching criteria.
