针对红外动态伪装系统，提出了一种基于特征综合的红外动态伪装效果评估方法。根据红外侦测图像的特性，选择了亮度对比度、直方图特征、纹理特征和边缘形状特征等四种特征指标，分别统计背景图像与伪装图像之间四种特征的相似度。四种特征相似度在综合评估过程中所占的比重不固定，特征权重分配依据伪装图像特征序列数据的信息熵的大小决定。最后累加单幅伪装图像的四种特征值与特征权重的乘积，作为该幅图像的综合评价结果。在红外动态伪装系统上进行了试验，通过采集背景图像和序列伪装图像，验证了效果评估算法的可行性和有效性。红外动态伪装效果的评估结果可为优化伪装设计算法提供数据支撑。

The evaluation of camouflage effect is an important part of camouflage design. Aiming at the infrared dynamic camouflage system, an evaluation method of infrared dynamic camouflage effect based on feature synthesis is proposed. According to the characteristics of infrared detection images, four feature indexes, namely brightness contrast, histogram, texture and edge shape, were selected to calculate the similarity between background image and camouflage image. The similarity proportion of the four features in the comprehensive evaluation process is not fixed, and the feature weight distribution is based on the entropy of the disguised image feature sequence data. Finally, the product of four characteristic values and characteristic weights of a single camouflage image is added as the comprehensive evaluation result of the image. Experiments were carried out on the infrared dynamic camouflage system, and the feasibility and effectiveness of the algorithm were verified by collecting background images and sequence camouflage images. The results of dynamic infrared camouflage effect evaluation can provide data support for the optimization of camouflage design algorithm.
