Abstract

To improve efficiency of the compressed image retrieval, the techniques of the direct feature extraction in compressed domain are extensively emphasized. An algorithm directly computing moments from DCT domain is presented. Employing the algorithm, An image retrieval system based on the JPEG image is developed. The system are robust for the translation, rotation and scale transform with minor disturbance. The theoretical analysis and experimental results also demonstraten the system has good performance whether in retrieval efficiency or effectiveness.
