Abstract

We explore the representation capabilities of scattering transforms for the classification of hyperspectral images. We examine several types, including a recently developed technique called the Fourier scattering transform. This method is naturally suited for the representation of hyperspectral data because it decomposes signals into multi-frequency bands and removes small perturbations such as noise. We test on four standard hyperspectral datasets, and the results indicate that the Fourier scattering transform is effective at representing spectral data. We also present a spatial-spectral scattering transform that combines Wavelet and Fourier representations, and this method obtains significantly higher classification accuracies.
