| 摘 要： | 为检测复杂背景中的低信噪比(SNR) 点目标,提出了一种自适应带通门限检测算法。首先根据图像的信噪比选取合适的带通门限进行图像空间滤波,然后采用帧相关法进行时间滤波。实验结果表明,该算法可有效地抑制背景杂波的干扰、提高信噪比SNR ,检测出复杂背景下的低信噪比点目标,且易于实现。

| Abstract: | In order to detect the low SNR point moving target in the the condition of complicated background ,an adaptive bandpass threshold algorithm is presented in this paper. First ,select the appropriate bandpass threshold to image spatial filter ,then to frame relation temporal filter. The expeimental reaults show that the proposed method can effectively control the background ,greatly improve the SNR ,and detect the moving point target. It also can be easily realized. |
