A feature extraction method is proposed for contour or graph information retrieval. The procedure is based on morphologically processing the projection functions of the contour. The image of the contour is processed not only as a whole, but also divided into sub-blocks. The level of image partitioning may vary depending on the degree of feature decomposition required and the achieved discriminative capabilities. Simulation results are provided.
