Adptive vector quantization for image sequence coding
Hao Sun, Morris Goldberg · 2005
In this paper, new algorithms are presented for image sequence coding based upon the combination of frame replenishment and vector quantization. The results reported include both non-adaptive and adaptive vector quantization. The adaptivity is performed by replenishing the codebook according to the local statistics of the image sequence. A statistical model is used to initiate the adaptive operation. The experimental results demonstrate that good quality reconstructed image sequences at bit rate as low as 0.6 - 0.7 bits/pixel are obtained using adaptive algorithms.
