Abstract
An enhanced filtering method in Contourlet transform domain is proposed in this paper. According to local properties, SAR image will be firstly divided into homogeneous area, non-homogeneous area and edge area. Then average filtering method is applied to the homogeneous area, Contourlet transform de-noising method applied to the non-homogeneous area and edge area retained directly. It's proved that not only can we effectively eliminate the noise but also maintain edge details through this method. Compared with other classical filters, the capability to keep the edge details is stronger.
