Research On The Evaluation Of Camouflage Effect Based On Similarity

Camouflage is one of the most important protective measures in modern information warfare.Camouflage effect evaluation is an indispensable part in the military camouflage struggle.The survival and fighting ability of a target depends largely on the quality of camouflage.The main purpose of this paper is the evaluation of camouflage effect to solve the existing military targets in the subjective basis,for the problem of quantitative and qualitative methods,the camouflage effect is difficult to predict,by the similarity and the detection probability evaluation project to achieve the effect of camouflage,and through theoretical analysis and experiments respectively,camouflage effect on military targets in the test are verified and a detailed comparison.The main research results are as follows:1)A model of camouflage evaluation based on similarity is proposed.According to the characteristics of the index selection principle and the mechanism of visual attention priority,a comprehensive selection of structure features,statistical features,texture features and color features of the four technical indicators as the basis for similarity evaluation,the feature extraction algorithm,feature similarity and background camouflage camouflage patterns in the four index.According to the contribution degree of influence,the size of each feature index,using entropy method to design the weight allocation algorithm with camouflage performance,the weight of each index is determined by weighted similarity of each feature size,disguised as the evaluation data set,provides a theoretical basis and data for the late camouflage effect evaluation experiment.2)An evaluation model based on the probability of discovery is proposed.According to the requirements of the national military standard on camouflage performance,a test scheme was developed to test the probability of camouflage detection of three patterns under different backgrounds(Marine and woodland background),collect and analyze test data,and establish an evaluation model based on discovery probability.3)A camouflage evaluation system based on similarity is realized.By using the calculated similarity and the detection probability,a mathematical relationship model between similarity and discovery probability is established,and a camouflage effect evaluation system based on similarity is worked out,and the effectiveness and applicability of the system are verified.Evaluation results show that the evaluation system developed in this paper can achieve camouflage performance requirements,verifying the evaluation system of camouflage effect adaptability and effectiveness,realizing the quantitative engineering camouflage effect,provides a solution for the design and optimization of the current project in disguise.
