一种改进的用于合成孔径雷达图像相干斑抑制的双边滤波参数配置方法
A modified method to configure the parameters of the bilateral filtering for synthetic aperture radar image speckle reduction
摘要
Abstract
Bilateral filtering can effectively smooth synthetic aperture radar (SAR) images with preserving the edges, but it is difficult to configure the parameters of bilateral filtering to the optimum. The iterative method to configure the parameters with high precision and efficiency has been presented, but the iterative process may be aborted incorrectly. In this paper, we present a modified configuration method to get the optimal trade-off parameters, and give the proof of the convergence of the method. The experimental results on real SAR images show that the modified method can not only obtain equivalent visibility as the iterative method, but also higher accuracy of the gray value similarity variance than that under identical iterative precision. With the iterative precision improved, the convergence rate of the modified method is faster than that of the iterative method.关键词
