| 摘 要： | 在对SAR图像的分析和识别中,边缘的检测信息十分重要。针对传统的LOG算子的缺陷,本文提出了一种基于自适应中值滤波的改进LOG算子对SAR图像的边缘检测方法,在平滑图像内部区域的同时保留了更多的细节,提高了LOG算子对SAR图像的弱边缘检测能力,是一种有效的方法。

| Abstract: | The edge detection of SAR is very important for image analysis and recognition.Because of the defect of the conventional LOG,an improved LOG is therefore proposed.A method for adptive median filter are put forward to smooth image with more details instead of Gaussian filter.This method can improve the capability of LOG to detect the feebleness edge of SAR Imaging And is effective in edge detection of SAR image. |

| Keywords: | adptive median filter edge detection LOG operator SAR Imaging |
