Multi-level shape description technique

Image database querying has become a major area of research and received increased attention. Shape representation is one of the major problems in content-based image retrieval (CBIR). Shape representation generally looks for effective ways to capture the essence of the shape features that make it easier for shapes to be stored, recognized, compared against, and retrieved. In this paper, we shall present a structural shape representation and description technique, where object shape is represented at multiple levels of abstraction. This technique has been implemented in order to analyze its retrieval accuracy, the performance evaluation showed very remarkable and promising results.
