"WebYPERSPECTRAL unmixing (HSU) is an important technique for remote sensing hyperspectral data ex-ploitation. The task of HSU is to estimate the pure spectral sig-natures, called endmembers, and their corresponding fractions, called abundance, for each pixel of the hyperspectral image [1]. Thus, the spectral of pixels is resolved into a weighted " - Spectral unmixing of multispectral github
