基于图像特征与心理感知量的伪装效果评价方法

目标的探测概率是伪装效果评价的重要指标,在以往的评价方法中忽略了判读人员的心理因素。在统计决策模型基础上,通过定义4 个图像特征相似度,建立了单个图像特征量与心理感知量的关系,进行了5 个心理实验,找出了目标探测概率与心理感知量的关系。经过综合判读实践验证,该模型能够客观地得到目标的探测概率,为伪装效果评价提供新的方法。

Camouflage Assessment Method Based on Image Features and Psychological Perception Quantity

Detection probability is an important index of camouflage assessment. Based on statistical deci- sion model, the relationship between single image feature and psychological perception quantity is set up by defining the similarity of four image features. Five psychological experiments were carried out, and the relation between perception quantity and detection probability was found. The verification of target inter- pretation shows that the target detection probability can be obtained by the model objectively. A new method is provided for camouflage assessment.
