| 摘 要： | 红外图像序列中小目标的检测问题是当前的研究热点。为了检测起伏背景中的弱小目标,在理论分析的基础上提出了用Wiener滤波器去除起伏背景,然后进行自适应目标检测的小目标检测方法。采用连续采集的长波红外图像序列进行了实验研究,并给出了目标检测结果及其分析。结果表明,该算法能够从信噪比大于2.0的图像序列中检测出目标轨迹。

| Abstract: | The detection problem for small targets in IR image sequences is a hot topic nowadays. In order to detect small targets in IR clutter, an algorithm based on suppressing clutter background with Wiener filter and then detecting the small targets adaptively is put forward. Experiments are done with long-range IR image sequences, and results and analyses of these results are given. The results show that this algorithm can detect small targets within the IR image sequence with SNR higher than 2.0. |
