The Future of Hyperspectral Imaging [PDF]

open access: yesJournal of Imaging, 2019
The Special Issue on hyperspectral imaging (HSI), entitled “The Future of Hyperspectral Imaging”, has published 12 papers. Nine papers are related to specific current research and three more are review contributions: In both cases, the request is to propose those methods or instruments so as to show the future trends of HSI.

Enhancing hyperspectral image unmixing with spatial correlations [PDF]

open access: yes, 2010
This paper describes a new algorithm for hyperspectral image unmixing. Most unmixing algorithms proposed in the literature do not take into account the possible spatial correlations between the pixels.

Quality criteria benchmark for hyperspectral imagery [PDF]

open access: yes, 2005
Hyperspectral data appear to be of a growing interest over the past few years. However, applications for hyperspectral data are still in their infancy as handling the significant size of the data presents a challenge for the user community.

Hyperspectral image unmixing using a multiresolution sticky HDP [PDF]

open access: yes, 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 ...

Singular spectrum analysis for effective feature extraction in hyperspectral imaging [PDF]

open access: yes, 2014
As a very recent technique for time series analysis, Singular Spectrum Analysis (SSA) has been applied in many diverse areas, where an original 1D signal can be decomposed into a sum of components including varying trends, oscillations and noise ...

Hyperspectral Image Database Query Based on Big Data Analysis Technology [PDF]

open access: yesE3S Web of Conferences, 2021
In this paper, we extract spectral image features from a hyperspectral image database, and use big data technology to classify spectra hierarchically, to achieve the purpose of efficient database matching.

Volume Holographic Hyperspectral Imaging [PDF]

open access: yesApplied Optics, 2004
A volume hologram has two degenerate Bragg-phase-matching dimensions and provides the capability of volume holographic imaging. We demonstrate two volume holographic imaging architectures and investigate their imaging resolution, aberration, and sensitivity.

Nonlinear spectral unmixing of hyperspectral images using Gaussian processes [PDF]

open access: yes, 2012
This paper presents an unsupervised algorithm for nonlinear unmixing of hyperspectral images. The proposed model assumes that the pixel reflectances result from a nonlinear function of the abundance vectors associated with the pure spectral components ...

Evaluation of colour space effect on estimation accuracy of hyperspectral image by dimension extension based on RGB image

open access: yesSICE Journal of Control, Measurement, and System Integration, 2022
Recently, the utilization of hyperspectral images containing several hundred wavelength information has been increasing in various fields. If a hyperspectral image can be estimated from a low-cost RGB image that has only R, G, and B wavelength ...
