Mineral absorption feature extraction in vegetation covered region based on reference spectral background removal

Diagnostic absorption feature has the potential to be the key factor of mineral information extraction in vegetation-covered region. Reference Spectral Background Removal (RSBR) could simulate the background curve based on the reference spectral background, and eliminate the influence through the background removal process. In this paper, RSBR was introduced into to mineral absorption feature extraction from high vegetation density area. Experiments on simulated data validated its great potential in mineral exploration in vegetation-covered region.
