A low-cost hyperspectral scanner for natural imaging and the study of animal colour vision above and under water [PDF]

open access: yes, 2019
Hyperspectral imaging is a widely used technology for industrial and scientific purposes, but the high cost and large size of commercial setups have made them impractical for most basic research.

Joint Bayesian endmember extraction and linear unmixing for hyperspectral imagery [PDF]

open access: yes, 2009
This paper studies a fully Bayesian algorithm for endmember extraction and abundance estimation for hyperspectral imagery. Each pixel of the hyperspectral image is decomposed as a linear combination of pure endmember spectra following the linear mixing ...

Extended Subspace Projection Upon Sample Augmentation Based on Global Spatial and Local Spectral Similarity for Hyperspectral Imagery Classification

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Band redundancy and limitation of labeled samples restrict the development of hyperspectral image classification (HSIC) greatly. To address the earlier issues, the classification models such as subspace-based support vector machines, which have gained a ...

High-resolution cathodoluminescence hyperspectral imaging of nitride nanostructures [PDF]

open access: yes, 2012
Hyperspectral cathodoluminescence imaging provides spectrally and spatially resolved information on luminescent materials within a single dataset. Pushing the technique toward its ultimate nanoscale spatial limit, while at the same time spectrally ...

Implementation strategies for hyperspectral unmixing using Bayesian source separation [PDF]

open access: yes, 2010
Bayesian Positive Source Separation (BPSS) is a useful unsupervised approach for hyperspectral data unmixing, where numerical non-negativity of spectra and abundances has to be ensured, such in remote sensing.

Band Subset Selection for Hyperspectral Image Classification

open access: yesRemote Sensing, 2018
This paper develops a new approach to band subset selection (BSS) for hyperspectral image classification (HSIC) which selects multiple bands simultaneously as a band subset, referred to as simultaneous multiple band selection (SMMBS), rather than one ...

A New GPU Implementation of Support Vector Machines for Fast Hyperspectral Image Classification

open access: yesRemote Sensing, 2020
The storage and processing of remotely sensed hyperspectral images (HSIs) is facing important challenges due to the computational requirements involved in the analysis of these images, characterized by continuous and narrow spectral channels.

Sketch-based subspace clustering of hyperspectral images [PDF]

open access: yes, 2020
Sparse subspace clustering (SSC) techniques provide the state-of-the-art in clustering of hyperspectral images (HSIs). However, their computational complexity hinders their applicability to large-scale HSIs.
