摘要
人工判读数字图像过程中,人眼对目标与背景之间亮度差异的感知阈值受背景图像特征影响较大。在不同类型的背景条件下实施目标伪装时,应根据背景类型及相应的人眼感知阈值,提出目标与背景之间的亮度差别要求。为此,在基于液晶显示器的人眼判读试验基础上,研究了一般观察条件下人眼对典型背景图像中局部区域亮度差异的感知阈值,并构建了基于图像熵的人眼感知阈值模型,为实施目标伪装以及开展伪装效果评估提供参考。
In the process of manually interpreting digital images,the human eye's perception threshold for brightness differences between targets and backgrounds is significantly influenced by the characteristics of the background image.When implementing target camouflage under different types of background conditions,it is essential to specify the required brightness difference between the target and the background based on the background type and the corresponding human eye perception threshold.Therefore,this study examines the perception threshold for brightness differences in local areas of typical background images under general observation conditions,using experiments based on LCD displays.Additionally,a human eye perception threshold model based on image entropy is constructed,providing a reference for the implementation of target camouflage and the assessment of camouflage effectiveness.
