| 摘 要： | 分析了红外图像中小目标、噪声以及背景的特点,考虑到单帧图像处理不能兼顾对目标的可靠检测和低的虚警概率,而现有的多帧检测算法计算量大,难以实时实现,采用了将单帧和多帧检测有机结合的小目标检测技术.首先采用基于高阶统计量的目标检测算法,从单帧强噪声图像中检测出虚警率低的候选目标点;然后针对小目标运动的一致性和连续性,采用多帧高阶互相关的序列图像处理方法,得到目标运动轨迹;最后再对目标运动轨迹进行综合评判,进行航迹确认,得到真实目标的位置和轨迹.实验结果表明,该技术降低了虚警概率,提高了检测概率.

| Abstract: | The characteristics of small targets, noise and background in infrared images are analyzed.On the research of small target detection, because of low detect rate and high false alarm of single frame processing, and complexity of multi-frame processing, a small target detect technology conjunct with single frame processing and multi-frame processing is proposed.It firstly separates candidate target from strong Gaussian noise in single frame based on high order statistics, then use high order correlation to pr... |
