Endmember extraction and spectral unmixing is a very challenging task in multispectral/hyperspectral image processing
due to the incompleteness of information. In this paper, a new method for endmember extraction and spectral unmixing
of hyperspectral images is proposed, which is called as minimum distance constrained nonnegative matrix factorization
(MDC-NMF). After being compared with a newly developed method named MVC-NMF, MDC-NMF not only has been
demonstrated more reasonable in theory but also shows promising results in the experiments.
