摘　　要：结合伪装效果评价的要求,以中国颜色体系为基础,建立了CIE1976L*a*b*、LMS、lαβ这3种颜色空间的64级亮度分量数据库,利用灰度直方图相似度算法,分析了以上3种亮度分量在伪装效果评价中的应用问题。实验结果表明,L*分量具有均匀性较好,Lm分量和l分量分别在灰度较低和灰度较高时,其伪装效果的评价结果与人眼判读结果相一致。Basing on the regulations of camouflage effectiveness evaluation and the Chinese color system, the database of 64-level luminance components of CIE1976L＊a＊b＊ ,LMS and lαβcolor space is established, and using the histogram similarity of gray degree,the applications of above three luminance components in camouflage effectiveness evaluation are analyzed.The results show that L＊ component has the good uniformity,Lm component and l component are consistent with the interpretation results of human eye,respectively in the lower and the higher gray level.
