摘要

为检测弱小红外运动目标,提出了一种基于高阶累积量投影的检测算法。红外图像序列经背景抑制后,首先计算时域数据的归一化三阶累积量,并将其投影到二维空间,然后在二维空间内对目标轨迹进行统计判决,以实现目标检测。推导出了目标和噪声在二维投影空间中的分布公式。通过与相关算法对比分析,该算法计算量小、检测率随目标信噪比增长较快。利用实际录制的图像序列进行了仿真实验,成功检测到了信噪比不小于2、像面运动速度为2帧/像素的目标,验证了算法的有效性。

Abstract

In order to detect moving infrared dim and small target, a novel high-order cumulant projection algorithm was proposed. After background of infrared image sequence was suppressed, the normalized 3-order cumulant of temporal data was projected to 2-dimensions domain, and then target was detected by searching possible track in 2-dimensions domain. The statistic distribution expressions of target and noise in 2-dimensions domain were established. Compared with concerned algorithms, calculation load of the new algorithm is lower than that of other algorithms and detection rate of the new algorithm increases quickly with Signal-to-Noise Ratio (SNR) improvement. A simulation experiment with actual infrared image sequences was done to prove the validity of the new algorithm, and the targets with SNR no less than 2 and speed in image equal to 2 frames/pixel were successfully detected.
