| 摘 要： | 提出了一种新的红外图像序列中快速运动小目标时域模型.为差分图像序列中的背景像素、目标像素、杂波像素建立了模型,将目标检测问题转化为噪声中已知信号的检测问题,并应用相关检测技术进行目标检测.理论分析表明,在SNR和SCR均大于6的情况下,算法具有很好的性能,实验结果也证实了算法的有效性.

| Abstract: | A new model for fast small target in IR image sequence was put foreword. Models for background pixel, target pixcel, clutter pixel in the differential image sequence were given. The proplem of targets detection was converted to the detection of a known signal in noise and correlate technique was used to detect targets in IR image sequence. Theoretical analyses shown that this algorithm could detect small targets in IR image sequence with SNR and SCR higher than 6.0. Experiment results also proved the validity of the algorithm. |
