摘要
针对SAR图像相干斑滤波中存在的降低相干斑与有效保持细节信息这一矛盾,研究了常用空域滤波算法,在此基础上,将中值滤波与增强LEE滤波相结合,改进了LEE滤波算法,该方法能够在滤除相干斑的同时很好地保持图像的边缘及细节纹理信息。
In the light of contradiction of reducing speckle and effective keeping details in Speckle filtering for SAR images,this paper studied the common speckle noise filters in spatial domain.On this basis,the median filter was combined into the enhanced Lee filter and thus improved the LEE filter algorithm.This method can filter the speckle noise and well maintain the image edges and details of the texture information.
