Query: Application of the Second-Order Statistics for Estimation of the Pure
  Spectra of Individual Components from the Visible Hyperspectral Images of
  Their Mixture   The second-order statistics (SOS) can be applied in estimation of the pure
spectra of chemical components from the spectrum of their mixture, when SOS
seems to be good at estimation of spectral patterns, but their peak directions
are opposite in some cases. In this paper, one method for judgment of the peak
direction of the pure spectra was proposed, where the base line of the pure
spectra was drawn by using their histograms and the peak directions were chosen
so as to make all of the pure spectra located upwards over the base line.
Results of the SOS analysis on the visible hyperspectral images of the mixture
composed of two or three chemical components showed that the present method
offered the reasonable shape and direction of the pure spectra of its
components.
