摘　　要：为了客观地评价目标的可见光伪装效果,提出了一种综合主色直方图和主色空间分布信息熵的评价方法。首先,提取目标和背景中的主要颜色;其次,计算主色的直方图和空间分布信息熵,分别用来表示主色的统计信息和分布信息;再次,根据色差最小原则将目标和背景图像的主色配对;最后,通过计算目标和背景色差最小主色对的色差和熵差来计算目标与背景的融合程度,进而评价目标的伪装效果。仿真实验证明,该方法评价结果与目视观察结果具有较好的一致性。A new method combining the histogram and information entropy of dominant colors was proposed to assess a target′s visible light camouflage effectiveness.Firstly,the dominant colors were extracted from both the target and its background images.Secondly,the histogram of every dominant color was calculated to represent the statistic information,and the space distributing information entropies were calculated to describe the distributing information.Thirdly,the dominant colors of the target and backgrounds were matched pairs by the principle of minimum color difference.Finally,the difference of color and entropy between colors of every pair was calculated to get the similarity between the target and its background.Based on this similarity the camouflage effectiveness was assessed.The results of experiments testify the feasibility of this method.
