Spectral information obtained by hyperspectral sensors enables better characterization, identification and classification of the objects in a scene of interest. Unfortunately, several factors have to be addressed in the classification of hyperspectral data, including the acquisition process, the high dimensionality of spectral samples, and the limited availability of labeled data. Consequently, it is of great importance to design hyperspectral image classification schemes able to deal with the issues of the curse of dimensionality, and simultaneously produce accurate classification results, even from a limited number of training data. To that end, we propose a novel machine learning technique that addresses the hyperspectral image classification problem by employing the state-of-the-art scheme of Convolutional Neural Networks (CNNs). The formal approach introduced in this work exploits the fact that the spatio-spectral information of an input scene can be encoded via CNNs and combined with multi-class classifiers. We apply the proposed method on novel dataset acquired by a snapshot mosaic spectral camera and demonstrate the potential of the proposed approach for accurate classification.
