16 September 1996 Reduction of specific distortions in image vector quantization
Author Affiliations +
In this paper, to reduce the specific distortions that accompany the vector quantization (VQ) process, we present the following VQ algorithms: (1) wavelet VQ (WVQ), (2) residual and hybrid residual VQ, and (3) VQ with a sorted codebook (VQ-SCB). The simulation results of the above mentioned algorithms have shown that a considerable reduction of the VQ specific distortions (PSNR equals 27.7 - 30.6 db) can be achieved at bit rates R equals 0.4 - 0.7 b/p.
