根据是否联合利用超光谱图像的空间和光谱信息，高光谱图像去噪技术能够分为两类。第一类就是将传统 2-D 图像去噪的方法直接应用到超光谱图像的每一个频带上去，称为逐带去噪。第二类就是联合利用空间和光谱信息来进行去噪，称为联合去噪，这又能够大体分为基于变换域的方法和基于空间域的方法。除此以外，因为深度理论的兴起，最近也出现了一些基于深度学习的超光谱图像去噪方法。php

然而，这些逐带去噪方法一般致使更大的频谱失真，由于没有同时考虑不一样频带之间的空间和频谱信息的相关性。html

联合去噪

1) 基于变换域的方法

基于变化域的方法尝试经过不一样的变换来将干净信号从噪声数据中分离出来，好比主成分分析、傅里叶变换、小波变换。git

这一类方法的主要缺点是它们对变换函数的选择很敏感，而且没有考虑超光谱图像几何特征的差别。github

2) 基于空间域的方法

采用合理的假设或先验，如谱间全局相关性(Global Correlation along Spetrum) 、空间非局部自类似性(Non-local Self Similarity across space)、总变差(Total Variation)、非局部(Non-Local)、稀疏表示(Sparse Representation)、低秩模型(Low Rank models)等，基于空间域的方法能够将噪声超光谱图像映射到干净图像而且保持其空间和光谱特征。app
