数码仿造迷彩客观定量评价

Objective Evaluation Method of Imitation Digital Camouflage

为了客观定量评价数码仿造迷彩的伪装效果,根据人眼视觉特性,提出基于HSV颜色空间亮度差的权重因子对SSIM算法加权进行了改进,得到了从人眼视觉特性上客观定量评价数码迷彩图案与原图像的识别概率。识别概率的大小与目标实施伪装技术的优劣有关,识别概率越高,则目标越易被侦察器材识别,伪装效果越差,反之不易被识别,伪装效果越好。因此该算法可为进一步改进伪装技术措施提供依据。

To evaluate the camouflage effect of imitation digital camouflage, according to human visual system, a weight fac-tor of color space brightness difference basd on HSV is proposed and improved algorithm on SSIM, from which the recognition probability can be derived on painting pattern and original image. The recognition probability related on camouflage technolo-gy, the higher of the recognition probability, the target is easy to be identified, the camouflage effect is worse. Conversely, the target is not easy to be identified and the camouflage effect is better. Therefore the algorithm prosed can provide improve-ment of camouflage technology measures.
