Image retrieval system based on combined MPEG-7 texture and Colour Descriptors

The MPEG-7 standard is one of the first to address the issue of multimedia content with full attention. It aims to set up a standard framework for describing all aspects of items audiovisual data, including low-level descriptions of objects in an image (such as shape, texture, colour and motion). By choosing a particular set of MPEG-7 texture and colour descriptors and testing them both individually, and in various combinations, this paper proves that texture and colour descriptors binded together provide better results than when used separately. The experiments results show that Edge Histogram Descriptor mixed with combined Colour Layout Descriptor, Scalable Colour Descriptor256, and Colour Structure Descriptor and Edge Histogram Descriptor mixed with Scalable Colour Descriptor256 give most satisfying image retrieval effectiveness.
