摘　　要：伪装目标与背景的综合相似度能够衡量伪装目标与周围背景之间的特征差异,综合相似度越高,目标与背景的融合程度越高,目标伪装效能越高。组合使用目标及背景图像的亮度、颜色、纹理、形状、尺寸、结构、直方图等7个典型特征来表征目标伪装特性,采用与其相应的相似度量法得到各个特征相似度,采用熵权法客观确定不同特征指标权重,线性加权得到伪装目标与背景的综合相似度,从而获得量化的目标伪装效能评估结果。不同背景、不同侦察距离、不同目标姿态下的多组实验表明:所提伪装目标与背景的综合相似度具有与目标发现概率一致性、与探测距离一致性、背景鲁棒性,证明了所提方法的正确性和有效性;并通过对比实验验证了该方法的可靠性。The comprehensive similarity between the camouflage target and the background can measure the feature difference between the camouflage target and the surrounding background.The higher the comprehensive similarity,the higher the fusion degree between the target and the background,and the higher the camouflage efficiency of the target.In this paper,seven typical features of target and background images,including brightness,color,texture,shape,size,structure,and histogram,are used to represent the camouflage characteristics of the target.The corresponding similarity measurement method is used to obtain the similarity of each feature.The entropy weight method is used to objectively determine the weights of different feature indicators,and the comprehensive similarity between the camouflage target and background is obtained by linear weighting.Thus,the quantitative evaluation results of target camouflage effectiveness can be obtained.Multiple experiments under different backgrounds,different reconnaissance distances and different target attitudes show that the comprehensive similarity between the camouflage target and the background proposed in this paper is consistent with the target discovery probability,consistent with the detection distance,and robust to the background,which proves the correctness and effectiveness of the proposed method.The reliability of the proposed method is proved by comparison experiment.
