Hyperspectral Upper-Bound Spectrum

Sandia Hyperspectral Upper-Bound Spectrum (Sandia Hyper-UBS) v 1.0

Download (Matlab Code)

Sandia Hyper-UBS is designed to remove cosmic ray spikes from hyperspectral data sets. This software was based upon the UBS-DM algorithm by D.M. Zhang and D. Ben-Amotz.1 The UBS-DM-HS algorithm is designed to be more robust and is better at removing cosmic ray spikes which impact multiple pixels. See the associated journal article2 for more details. Sandia Hyper-UBS also provides implementations of the other algorithms tested in the journal article.
