摘要
为促进非局部均值滤波在PolSAR相干斑抑制技术领域的应用与发展,首先简要阐述了非局部均值滤波的基本理论;然后系统梳理了非局部均值在PolSAR相干斑抑制处理中应用的历史沿革,最后深入探讨了现有研究工作的不足之处及其解决之道,为该方向进一步开展研究工作提供有益参考。
In order to push forward the application and development of NLM filter in the field of PolSAR denoising technology, the basic theory is firstly introduced briefly. Then, the evolution of NLM filter is elaborated systematically. Finally, the deficiencies of these NLM algorithms are addressed and the directions of solutions to these problems are pointed out. These efforts may be desirable to be used as a reference for the further studies in the field of PolSAR denoising.
