SAR图像双边滤波算法及MATLAB仿真实验

SAR Image Bilateral Filtering Algorithm and MATLAB Simulation Experiment

本文研究了双边滤波算法及其在SAR图像中的滤波性能,进行MATLAB仿真实验,并与其他几种常见滤波算法做了对比,用等效视数、边缘保持因子这两个客观指标进行评价。实验表明,双边滤波在SAR图像平滑斑点噪声和边缘纹理保持方面具有更大的优势。

This article studies the bilateral filtering algorithm and its filtering performance in SAR images,conducts MATLAB simulation experiments,and compares it with several other common filtering algorithms,using two objective indicators,equivalent sight number and edge retention factor evaluation.Experiments show that bilateral filtering has greater advantages in SAR image smoothing speckle noise and edge texture preservation.
