An Enhanced Generalized Lloyd Algorithm
C.-Q. Chen · IEEE Signal Processing Letters · 2004
Vector quantization is an effective means of data compression for it maps a set of real numbers into a single integer. In this letter an enhanced generalized Lloyd algorithm (GLA) for vector quantizer design is presented. Experiment results show that the proposed scheme outperforms the conventional GLA and recently reported modification of the K-means algorithm. Moreover, the achievement in coding performance is not accompanied by significant increase in computational complexity.
