A novel Predictive Vector Quantization system in color image coding

Predictive Vector Quantization (PVQ) is the combination scheme of Predictive Coding (PC) and Vector Quantization (VQ). The performance of the PVQ system would be projected from complexity of the predictor and fidelity of the decoded image. In this paper, three novel predictors are suggested to enhance the performance of existing PVQ system. Different schemes would be compared among their coding fidelity of the decoded image. The improvement in both the quantitative and qualitative qualities is significance in the color image coding
