Optimal quantization of JPEG2000 baseline compression in RGB space

In this paper, an optimal compression ratio is discussed based on JPEG2000 baseline compression in RGB space. Human eyes are more sensitive to green color than to red and blue colors. Hence, optimal compression ratios should be adopted during quantization. A novel mathematical model for co-relationship of three color components in RGB is developed. VDR (voyage data recorder) test methods combined with information entropy are used to evaluate the optimal compression ratio, considering the human eye characteristics. Simulation results have proven the effectiveness of the proposed method.
