Background Selection Method of Optical Camouflage Effect Evaluation Based on Color Clustering

doi:10.3969/j.issn.1000-1093.2021.03.018

Abstract

Abstract: In the camouflage effect evaluation of single target based on optical images，a large deviation in the evaluation results may be caused by taking the 8-neighborhood image of the target region as the background region when the target is near the boundary between different background areas with large contrast.To solve this problem，a background selection method based on color clustering is proposed.The color classes that are not included in the target neighborhood are removed from the color clustered 8-neighborhood image by the proposed method，and then the target region is subtracted to get the selected background. Experimental results show that the irrelevant background regions can be effectively removed when the image is clustered by 4-6 color cluster centers，so as to enhance the objectivity and accuracy of camouflage effect evaluation. The proposed method is suitable for different target location relationships.

Key words: opticalimage, camouflageeffectevaluation, backgroundselection, colorclustering
