A performance acceleration algorithm of spectral unmixing via subset selection
, 2017 An acceleration algorithm for spectral unmixing approach is proposed based on subset selection. The method classifies the pixels in a spectral image into accurate and approximated unmixing groups based on the similarity and dissimilarity of ...

Spectral unmixing of hyperspectral imagery using multilayer NMF
, 2015 Hyperspectral images contain mixed pixels due to low spatial resolution of hyperspectral sensors. Spectral unmixing problem refers to decomposing mixed pixels into a set of endmembers and abundance fractions.

Mineral mapping and landsat thematic mapper image classification using spectral unmixing
, 1997 In this paper, spectral image unmixing applied to Landsat Thematic mapper data from southern Spain is described to obtain a classified image based on abundance estimates of a number of spectral endmembers assuming linear mixing systematics.
