一种计算红外点目标检测概率的方法

Calculation of the detecting probability of an infrared point target

在红外成像系统中因为噪声的影响而导致目标检测的结果呈现出概率分布 ,检测概率常常被用来作为衡量算法检测性能的指标 .利用对比度门限检测给出了检测概率的计算方法 ,并给出了检测概率与信噪比。

In the IR imaging system, results of target detection are uncertain because of the affects of noise. Detection probability is generally used as a criterion to judge an algorithm for detection. This paper presents a method of calculating the detection probability under contrast threshold detection. The relationship of detection probability with SNR, contrast and threshold is also given.
