A query-based mechanism for geometrical objects retrieval in multimedia information system

The basic elements of a multimedia cognitive-based information retrieval system called AMCIRS which integrates image and text information have been described elsewhere. The AMCIRS query based mechanism is based on multimedia objects content search using the vector model. The content search process is deduced to the similarity estimation between query and index vectors. The paper introduces the similarity estimation model for geometrical objects as a part of a query mechanism of AMCIRS. The model for polygon similarity estimation introduces a numerical measure of similarity between two polygons and gives acceptable results for all polygon forms and any number of vertices. The algorithm based on this model as well as the simulation results are also given.<>
