To accurately pick up the colors of imitated pattern painting, the K-mean clustering algorithm based on CIE1976L* a* b* uniform color space was adopted, taking the RMSE function to evaluate. It is shown that the RESM of the background image and the 3 or 5 color cluster images are all less than 0. 1.Thus this method can not only avoid chromatic aberration by quantification of color space and make the imitated pattern painting perfectly fused with the background to fit the design of the pattern painting camouflage, but also provide a basis for the automatic design.%为了正确选取仿造迷彩的颜色,采用基于CIE1976L*a*b*均匀颜色空间的K-mean聚类算法将均方根误差函数作为评价函数.仿真结果表明背景图像与其三色和五色聚类图像的均方根误差均小于0.1.此算法可避免人为地在颜色空间上量化带来的色差,能与背景更有效地融合,更好地满足迷彩伪装设计要求,同时也可为仿造迷彩自动化设计提供基础.
