摘要
文章根据高分辨率SAR图像特点,考虑到SAR图像滤波要保证平滑效果的同时保证边缘结构信息的尽量完整性,基于现有增强算法的思想,提出了一种基于维纳滤波及小波软阈值滤波的综合型滤波器,实验表明文中提出的滤波器相对现有的滤波算法有更好的性能。
This paper proposes a synthesizing type filter based on Wiener filtering and wavelet soft-threshold filter for high-resolution SAR images by considering SAR images＇features,the requirement of ensuring both effective smoothness and marginal texture to the greatest extent,and the idea of existing filtering algorithm.And the experiments show that the proposed filter has relatively better performance than the existing filtering algorithms.
