Vertex component analysis: a fast algorithm to unmix hyperspectral data
TL;DR: A new method for unsupervised endmember extraction from hyperspectral data, termed vertex component analysis (VCA), which competes with state-of-the-art methods, with a computational complexity between one and two orders of magnitude lower than the best available method.
Journal ArticleDOI
Hyperspectral Subspace Identification
TL;DR: This paper introduces a new minimum mean square error-based approach to infer the signal subspace in hyperspectral imagery, which is eigen decomposition based, unsupervised, and fully automatic.
Journal ArticleDOI
Does independent component analysis play a role in unmixing hyperspectral data
TL;DR: The accuracy of these methods tends to improve with the increase of the signature variability, of the number of endmembers, and of the signal-to-noise ratio, and it is concluded that there are always endmembers incorrectly unmixed.
Proceedings ArticleDOI
Nonlinear mixture model for hyperspectral unmixing
TL;DR: In this paper, a semi-supervised unmixing method is proposed and evaluated with simulated and real hyperspectral data sets, where the second-order scattering interactions are assumed negligible.
Journal ArticleDOI
Hyperspectral Unmixing Based on Mixtures of Dirichlet Components
TL;DR: A cyclic minimization algorithm is developed where the number of Dirichlet modes is inferred based on the minimum description length principle, thus automatically enforcing the constraints on the abundance fractions imposed by the acquisition process.
