Abstract
In this paper, a new index compression algorithm is proposed for efficient VQ coding of images. The proposed algorithm tries to exploit the high correlation between neighboring image blocks in the VQ index domain in order to achieve further compression. Simulation results show that the proposed scheme can achieve 40% bit-rate reduction without introducing any extra coding error when compared with a standard VQ system.
