| 摘 要： | 从分析传统的差分法难于检测出低信噪比图像序列运动目标的原因入手，剖析了噪声对运动目标检出的影响，提出了消除噪声影响的方法，进而提出了一种抗噪能力很强的检出运动目标的新方法－－模板对准相乘法。设计了３种不同形式的模板对准相乘法，即差分模板对准相乘法、时间拉普拉斯模板对准相乘法和空间拉普拉斯模板对准相乘法；详细地描述了这３种方法的具体实现步骤和适用范围，对低信噪比图像序列进行处理的结果表明，模板对准相

| Abstract: | The effect of noise on detecting motive objects in image series is analyzed in view of the reason that traditional calculus of differences are difficult to detect their motive objects with lower SNR,and a method of eliminating the influence of noises,template aimed multiplication with high anti noise ability to detect motive objects,is proposed Three different ways are designed, which are template aimed multiplying, time Laplas template multiplying, and space Laplas template aimed multiplying.Their operation steps and applied ranges are described in detail. |
