Hyperspectral Imaging Techniques in Search of Geologic Hydrogen: A Review
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingNew energy sources are crucial for powering next-generation transportation and supplying reliable energy in remote regions. Hydrogen is an attractive energy carrier because its utilization produces only water as a byproduct.

Hyperspectral image unmixing using a multiresolution sticky HDP [PDF]
, 2012 This paper is concerned with joint Bayesian endmember extraction and linear unmixing of hyperspectral images using a spatial prior on the abundance vectors.We propose a generative model for hyperspectral images in which the abundances are sampled from a ...

Rethinking Separability Map: A Target-Specified Separability Map for Hyperspectral Target Detection
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSeparability map (SM) is a widely used visualization tool for hyperspectral anomaly detection. It selects a fixed percentile range of [τSM%,100%-τSM%] and then uses it to construct an anomaly box (ax) and a background ...

Advanced Intelligent Systems, EarlyView.This study assesses the suitability and performance of single‐image super‐resolution methods when applied directly, and without any fine‐tuning, to multispectral images of maize and sunflower crops. It evaluates not only super‐resolution performance, but also the preservation of spectral integrity and vegetation‐index reliability. Multispectral imagery

Archaeological Prospection, EarlyView.ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.
