In order to sufficiently utilize the motion information, the feature images of multi-frame are cumulated to improve the detection probability and reduce the false alarm rate.

为了充分利用目标的运动信息，连续多帧图像的融合特征图像进行能量累积，达到进一步提高检测概率，降低虚警率。

Results from the working system show that the method holds features of high detected probability and low constant false alarm rate(CFAR) in the environment of changing nature beam.

系统运行结果表明，对于自然光线变化的场合，该方法具有检出率高、虚警率低的特点。

If one in 1, 000 people have a disease and the false-positive rate for a test is 5%, then the probability that a person testing positive has the disease is at most 2%.
