An investigation of data compression techniques for hyperspectral core imager data

By Kerry-Anne Cawse, Steven Damelin, Louis du Plessis, Richard McIntyre, Michael Mitchley and Sears Michael


We investigate algorithms for tractable analysis of real hyperspectral image data from core samples provided by AngloGold Ashanti. In particular, we investigate feature extraction, non-linear dimension reduction using diffusion maps and wavelet approximation methods on our data
