一种基于高通滤波的背景抑制方法

Background Suppression Algorithm Based on High-pass Filter

将复杂背景下的小目标检测问题看作是在大量相似模式中寻找某个特殊模式的模式识别问题,用该方法对图像进行多级高通滤波处理可进一步改善处理效果。实验结果表明,该方法能有效抑制背景杂波,提高对目标的单帧检测能力。

Small target detection in complex backgrounds is considered as a problem of finding the special patterns in similar patterns. Multi-level high-pass filter processing is presented to improve treatment effects. Experimental results show that the approach proposed is effective in detecting the small targets in clutter.
