  • 摘要: 该文针对在极化合成孔径雷达(PolSAR)图像相干斑抑制过程中结构特征和极化散射特性保持的难题,提出一种基于同质像素预选择的非局部均值滤波算法(NLM-HPP)。该算法结合像素统计特性和极化散射机制选择滤波同质像素,并引入结构损失函数提高非局部均值(NLM)算法中像素间相似性度量的准确性,最后用改进的相似性度量对同质像素的协方差矩阵进行加权平均,实现对PolSAR图像的相干斑抑制。对真实PolSAR数据进行的实验结果表明,与现有的Refined Lee滤波、基于散射模型的滤波方法和两种非局部均值滤波相比,此方法在有效滤除相干斑点的同时能更好地保持PolSAR图像的结构信息和极化信息。
