激光干扰图像质量的交叉熵评估

doi:10.3969/j.issn.1001-2400.2014.05.022

Abstract

Abstract:

A method for assessing the quality of disturbed image uses the cross entropy of the image for the problem that the imaging-guided weapons are liable to suffer laser interference by combining with the principles of guided tracking and anti-jamming mechanism. It is on the basis of the concept of cross-entropy in information theory that the method is presented. Analyses of similarity between images before and after disturbing are made to decide the evaluation function which combines the advantages of cross-entropy and the process of image quality assessment. The validity of the function derived is analyzed theoretically and experimentally. Experimental results are presented, and the method for the quality assessment of the laser disturbed image based on cross entropy can accurately obtain the threshold when laser interference is successful, so it is widely applicable to laser disturbing image quality assessment.

Key words: cross entropy, image quality assessment, optical seeker, correlation peak
