为解决有效地去除斑点噪声和保留图像边缘两者矛盾的问题,首先通过中值滤波得到较好的平滑SAR图像,然后利用AMSS方程得到较好的保留图像边缘信息的SAR图像,最后将所得的两幅图像进行融合,并对融合后的图像进行定量和定性分析。仿真实验表明,无论是定性分析,还是定量分析都证明融合后的图像在很好地去除噪声的同时,有效地保留了图像的地物分界处及边缘细节信息。
In order to solve the problem of effectively removing the speckle noise and preserving the contradiction between the image edges, we first obtain the smoothed SAR image through median filtering, and then use the AMSS equation to get a better SAR image which preserves the image edge information. Finally, The two images are fused, and the fused images are quantitatively and qualitatively analyzed. Simulation results show that both the qualitative analysis and the quantitative analysis prove that the fused image can effectively remove the noise and preserve the image detail and the edge details effectively.
