Evaluation Of Infrared Camouflage Based On Digital Image Processing Algorithm

Infrared camouflage technology is applied widely and deeply in the military field,and it directly affects and even determines the viability of military targets.So,it is fully necessary to evaluate the effectiveness of target’s camouflage.Most of existing assessment of camouflage effectiveness is based on computer digital image processing which is the study of feasibility in a single point of view,or it is based on subjective judgement from experts’ experience in general perception.Both above don’t come into being a complete system nor bring about a scientific and effective comprehensive evaluation.Therefore,this paper is aimed at evaluating effectiveness of target’s camouflage with the combination of muti-view objective parameters and subjective visual perception.All around above,the following work is carried out in this article:First of all,the research determines three aspects: target’s texture feature,fuzzy uncertainty,structural similarity between target and typical background as objective parameters for camouflage evaluation.It is feasible that these features could be regarded as representative ones which can distinguish targets from background.In the experiment of texture feature analysis,the study makes use of contrast characteristics based on GLCM to analyse the texture law of whole scene,typical background and targets with camouflage or not in a large range of scale,affect to texture in different environment as well.Then,representative scale and the texture changes are obtained to design and calculate the texture feature evaluation parameter of camouflage effectiveness.Fuzzy uncertainty study applies “fuzzy distance” based on intuitionistic fuzzy set which is associated with Gamma and Sugeno for analysing the “distance” between the target and typical background,also,different environment is considered.After that,the changes of uncertainty are obtained to design and calculate the fuzzy uncertainty evaluation parameter of camouflage effectiveness.The research of structural similarity which is based on SSIM analyses the features between the typical background and target with camouflage or not,the changes in different environment are taken into account as mentioned above.Followed,the structure changes are obtained to design and calculate the similarity evaluation parameter of camouflage effectiveness.This paper combines analytic hierarchy process-fuzzy comprehensive evaluation method and feature evaluation parameters of camouflage effectiveness to compute the score by establishing judgment matrix and fuzzy matrix.Finally,comprehensive evaluation of camouflage is completed.
