摘要
提出了利用红外图像的分形特征评价伪装效果的新方法.首先获得目标伪装前后的红外图片;然后运用"毯覆盖"法,计算了伪装前后目标与周围6处背景的分形维数;最后通过伪装前后目标与背景分形维数的差异分析它们的相似性,结果表明,伪装后目标与背景的相似性明显的增强.初步验证了分形应用于伪装效果评价是可行的.
A new method to evaluate camouflage effectiveness by using the fractal character of infrared image was put forward. Infrared images of the object before and after camouflage were obtained. The fractal characters of the object and six around backgrounds before and after camouflage through Covering-Blanket were calculated. The comparability between the object and around backgrounds by the difference of their fractal characters was analyzed. The experiment result shows that comparability of the object and natural background before and after camouflage is enhanced, and the fraction is available to evaluate camouflage effectiveness.
