根据目标、背景干扰和噪声在红外序列图像中的差异,提出了一种基于空间高通滤波和时间域上N帧轨迹积累的运动小目标检测方法.该方法可以在低信噪比的情况下消除红外起伏和随机噪声的影响,有效检测出弱小目标.实验结果表明,采用这种时空混合处理的方法可以得到满意的结果.

According to the imaging difference of target, background clutter and noise, a moving small target detection method based on spacial high-pass filtering and N-frame track accumulating is presented. The method can eliminate the effect of IR clutter and random noise in low signal-to-noise ratio, and can effectively detect the weak small target. Experimental results show that the satisfactory processing result is obtained.
