| 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 ... |
