Abstract:

A classification method of hyperspectral images based on deep 3D convolution networks is proposed in order to deal with the high dimensional and small samples of hyperspectral image classification. The method first uses hyperspectral data cube as input, and uses 3D convolution operation to extract 3D spatial-spectral features of hyperspectral data cube. Then, the residual learning is used to construct the deep network and extract higher level feature expression to improve the classification accuracy. Finally, the Dropout regularization method is used to prevent overfitting. Experiments were conducted on the University of Pavia, Indian Pines and Salinas datasets, and the results demonstrate that compared with support vector machine and the existing deep learning classification method for hyperspectral images, the method can effectively improve the classification accuracy of hyperspectral image.
