HSI-SVM

简介

  针对高光谱遥感影像识别与分类中存在的问题,开展了以下几方面的研究工作。

  • 针对在实际应用中,当特征维数增加到某一个临界点时,继续增加特征维数反而会导致分类器的性能变差,即出现所谓的"休斯(Hughes)现象"的问题。提出了基于波段组合(2D)2PCA 的高光谱遥感影像降维方法,达到了降低数据冗余,消除"休斯现象"的目的,为后续的特征提取和分类工作奠定了基础。
  • 提出了基于双通道卷积神经网络的HSI空谱特征提取模型,该模型综合利用了高光谱遥感影像中所包含的光谱特征和空间特征,可有效的提高识别和分类的效率。
  • 针对分类器的泛化能力较弱的问题,提出了基于双通道CNN-SVM相融合的HSI识别与分类模型,该模型充分利用了卷积神经网络强大的图像特征提取能力,同时将SVM的泛化能力最大化,最大限度的提高了模型的分类精度,并将该模型应用到高光谱遥感影像分类中。
