     With the increased interest in indexing biomedical images with an automated or computer-aided retrieval system, we have tried to develop a more accurate system that continually analyzes feedback from users. Shape-based retrieval techniques show a great potential for this task although it's still very challenging because of highly similar shape properties. In this research, the focus is on locating nine anatomy relevant contour points that match closely with the 9-point model used by the expert for image retrieval ranking.
