Paper Abstract

An efficient image compression technique using block grouping is presented. The similar blocks in an image are merged into a group in a recursive manner. The center of a group is then encoded with the Joint Photographic Experts Group (JPEG)-like algorithm. Simulation results indicate that the proposed algorithm improves the compression efficiency significantly, compared with the JPEG-like algorithm.
