| 摘 要： | Introduction The need for quantization of color images isarised because of the limitations of image displayand hardcopy,data storage and data transmissiondevices.The color image quantization is a complexdata clustering problem due to the broad distribu-tion of local optima in the three- dimensional colorspace. Many of the present algorithms for colorquantization find non- optimal solutions,giving riseto visible shifts in color and false contours whenthe number of quantization colors is sma…

| Abstract: | An evolutionary programming based algorithm was proposed for color image quantization. A novel hybrid mutation operator was disigned to improve the quantization quality, and a stochastic sampling scheme was also presented for saving the run time. The experimental results demonstrate the superior performance of the proposed algorithm in comparison with the GA based algorithm. |
