Signal Recovery on Graphs: Random versus Experimentally Designed Sampling
Siheng Chen, Rohan Varma, Aarti Singh +1
We study signal recovery on graphs based on two sampling strategies: random sampling and experimentally designed sampling. We propose a new class of smooth graph signals, called ap…
Robust hyperspectral image classification with rejection fields
Filipe Condessa, Jose Bioucas-Dias, Jelena Kovacevic
In this paper we present a novel method for robust hyperspectral image classification using context and rejection. Hyperspectral image classification is generally an ill-posed imag…
SegSALSA-STR: A convex formulation to supervised hyperspectral image segmentation using hidden fields and structure tensor regularization
Filipe Condessa, Jose Bioucas-Dias, Jelena Kovacevic
We present a supervised hyperspectral image segmentation algorithm based on a convex formulation of a marginal maximum a posteriori segmentation with hidden fields and structure te…
