چکیده
Abstract Vector Quantization is lossy data compression technique and has various applications. Key to Vector Quantization is good codebook. Once the codebook size is fixed then the MSE reaches a value beyond which it cannot be reduced by using codebook generation algorithms. In this paper we are proposing multilevel codebook generation algorithm. For demonstration we have used codebooks obtained from Kekre’s Fast Codebook Generation (KFCG) algorithm.

Two-level Vector Quantization Method for Codebook Generation using Kekre’s Proportionate Error Algorithm
Vector Quantization is lossy data compression technique and has various applications. Key to Vector Quantization is good codebook. Once the codebook size is fixed then for any codebook generation algorithm the MSE reaches a value beyond which it cannot be reduced unless the codebook size is increased. In this paper we are proposing two-level codebook generation algorithm which reduces mean squa...
متن کاملNovel codebook generation algorithms for vector quantization image compression
Novel algorithms for vector quantization codebook design are presented in this paper. Two basic techniques are proposed. The first technique takes into consideration specific characteristics of the blocks of the training sequence during the generation of the initial codebook. In this way a representative initial codebook is generated. Starting from a high quality initial codebook the iterative ...
