Abstract

The amount of information contained in a single hyperspectral image is overwhelming for the human operator. As a result, assessing the spatial and spectral variability of a hyperspectral image is very difficult. The existing techniques mainly rely on different preprocessing algorithms that reduce the high-dimensionality of the hyperspectral data down to a few images that can be visualized using traditional RGB or RGBI combinations. The proposed auto-correlogram approach provides a simple framework for reducing a hyperspectral image cube to a single grayscale image that is easy to interpret and screen for spectral anomalies.
