This thesis contributes methods that efficiently and robustly exploits superpixels for hyperspectral data. We study and quantify the efficacy of state-of-the-art superpixel generation algorithms for a variety of hyperspectral images. In this work, superpixel level analysis is proposed for two different hyperspectral image analysis problems — remote sensing image classification and person re-identification via forward looking hyperspectral imagery. Specifically, for remote sensing images, we propose a framework based on superpixels that provides spatial context for robust classification, and, for ground-based “natural” hyperspectral images, efficacy and utility of superpixels is demonstrated, in a multi-view setup, through a pilot study on a person re-identification task.","abstract_html":"With rapid development of multi-channel optical imaging sensors, hyperpsectral data has become increasingly popular, necessitating development of algorithms for robust image analysis with such data.
