Abstract :
One approach to reduce the bit rate required to encode the side information parameters in BTC image compression techniques is to employ joint vector quantization. The authors propose an alternative scheme which encodes with separate vector quantizers the arrays formed with each one of the parameters. Simulation results are presented and a comparative performance analysis shows the improvements achieved with the proposed quantization structure
