Abstract: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.
