Paper Abstract

In this paper, we new sub-region search algorithm is proposed for fast encoding of image vector quantization. In the proposed scheme, we will only search a portion of the codebook to locate the best match vector of each input vector according to the state of its neighboring blocks. A block transition criterion is developed for selecting the subset of codebook for searching. Simulation results show that the encoding time required by the proposed algorithm is just about 10 - 20% of that required by the full search with almost the same output image quality.
