Unsupervised Classification in Hyperspectral Imagery with Nonlocal Total Variation and Primal-Dual Hybrid Gradient Algorithm
Wei Zhu, Victoria Chayes, Alexandre Tiard +6
In this paper, a graph-based nonlocal total variation method (NLTV) is proposed for unsupervised classification of hyperspectral images (HSI). The variational problem is solved by…

Hierarchical Clustering of Hyperspectral Images using Rank-Two Nonnegative Matrix Factorization
Nicolas Gillis, Da Kuang, Haesun Park
In this paper, we design a hierarchical clustering algorithm for high-resolution hyperspectral images. At the core of the algorithm, a new rank-two nonnegative matrix factorization…
