  Abstract

In this paper, new image vector quantization method for improvement computation cost and compression ratio is proposed. A proposed method could saved the computation cost of codebook generation and encoding using partial codebook search, partial codevector elements, and interruption criterion. And, to improve compression ratio of codebook index lossless coding, codebook rearrangement and variable length coding scheme are used.
