摘要
根据斑点噪声的来源,分析和比较了抑制SAR图像斑点噪声的Lee滤波、Gamma MAP滤波、Frost滤波算法,并用台湾地区的SAR图像数据验证了不同滤波算法对斑点噪声的抑制效果.结果表明,Lee滤波抑制斑点噪声的综合性能最好.
According to the sources of speckle noises, different methods for speckle noise suppression, including Lee filtering, Gamma MAP filtering, Frost filtering, were analyzed and compared. With the data of spaceborne SAR images of Taiwan, the effects of speckle noise suppression of different filtering methods were validated, and the result shows that the performance of Lee filter is the best of all the three methods.
