Fast Unmixing of Noisy Hyperspectral Images Based on Vertex Component Analysis and Singular Spectrum Analysis Algorithms

open access: yesCanadian Journal of Remote Sensing, 2020
Efficient denoising is of great significance to unmixing hyperspectral images. In the present study, a fast unmixing method for noisy hyperspectral images based on the combination of vertex component analysis and singular spectrum analysis is proposed ...

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.
