Unsupervised spectral sub-feature learning for hyperspectral image classification

Viktor Slavkovikj, Steven Verstockt, Wesley De Neve, Sofie Van Hoecke, Rik Van de Walle
2016 International Journal of Remote Sensing  
In this article, we propose an unsupervised feature learning method for classification of hyperspectral images.  ...  Expanded hyperspectral feature representations enable linear separation between object classes present in an image.  ...  In contrast, we learn discriminative features by mapping in an expanded but sparse feature space, which allows for linear separability of the classes present in the hyperspectral image.  ...
