图像处理伪装图像评价容限近集近似测量 image processing camouflage-images evaluation tolerance nearness sets nearness measure

摘要

在对地面目标光学伪装评价的研究中，根据地面背景伪装图像的特点，提出了一种基于容限近集理论的评价地面目标光学伪装效果的方法。提取伪装图像中的目标和背景区域，将这些区域作为容限空间中的集合分别进行分块，每块子图像作为集合元素，提取各子图像的统计、颜色和纹理等特征，在容限空间中计算背景与目标并集集合的所有容限近似类，用近似测量(tNM)指标评价伪装效果，并将tNM与豪斯多夫距离（tHD）比较。结果表明，容限近似理论作为一种新的评价伪装图像伪装效果的方法能很好地代替人眼主观评价；tNM作为评价伪装效果的指标优于tHD。

Abstract

On the research of evaluating optical camouflage ground targets, a method using tolerance nearness sets to evaluate ground targets′ camouflage effect is proposed, according to the characteristics of the camouflage images. The targets and backgrounds are extracted from these images, which seen as different sets in tolerance space, and divided into numbers of sub-images. Several features such as statistics, color and texture characteristics are extracted from every sub-image and all of tolerance nearness class in background and object sets are calculated. Nearness measure (tNM) is used to evaluate camouflage effect and compared with Hausdorff distance (tHD). The results show that tolerance nearness sets method can well replace human eyes to evaluate camouflage effects and tNM is better than tHD as the evaluation index.
