Fast image retrieval based on color, texture and shape of MPEG-7

Color, texture and shape are three basic visual features in content-based image retrieval. Descriptors based on only one of them could just express parts of characteristics of images. This paper proposes a method that comprehensively utilizes domain color descriptor, edge histogram descriptor and shape feature descriptor in MPEG-7 standards, and evaluates the result according to the evaluation standards provided by MPEG-7. The experiment result shows that the method combining three features does more in line with the requirements of human visual experience, and obtains better retrieval result.
