Image Retrieval Technology of Multi-MPEG-7 Features Based on Genetic Algorithm

A content-based image retrieval (CBIR) system, especially the WEB-based CBIR system must be able to acknowledge different interpretations, which can be universally passed onto or accessed by a device or a computer code whether they are from CBIR system itself or from outer. In addition, the CBIR system must consider the different angles of human visual system. In order to realize such functions, MPEG-7 is employed with the aim to provide fundamental tools for describing multimedia contents and genetic algorithm is used to optimize the retrieval feature spaces so as to make the retrieval universal and to get the best result set. Experiments show that the retrieval efficiency can be significantly increased in comparison with the efficient content-based image retrieval.
