Abstract

The technology to provide a key to the develop- ment of new methods of visual information indexing and retrieval is the extraction of the feature sets for the description of objects within images. Shape is one of the most important characteristics which allows us to distinguish and identify different objects. The appropriate usage of some properties of shapes, such as corners and their relative posi- tions or, in other words, feature points, can be high- ly beneficial for object similarity estimation that is essential for indexing and retrieval.
