Linear Estimation of Hyperspectral Mixed Pixel Components

Abstract

This paper presents a method to determine end members along with their relative concentration in a hyperspectral mixed pixel. The method is modeled as a linear combination of the end members reflectance spectra and a library of spectral prototypes. This method was tested with 431-band, laboratory controlled, data sets. Indications are that this method can be extended to field data observations with a small number of end members and that at least some error source can be identified and data and results adjusted accordingly.
