Hyperspectral Band Selection via Band Grouping and Adaptive Multi-Graph Constraint

open access: yesRemote Sensing, 2022
Unsupervised band selection has gained increasing attention recently since massive unlabeled high-dimensional data often need to be processed in the domains of machine learning and data mining.

Optimized kernel minimum noise fraction transformation for hyperspectral image classification [PDF]

open access: yes, 2017
This paper presents an optimized kernel minimum noise fraction transformation (OKMNF) for feature extraction of hyperspectral imagery. The proposed approach is based on the kernel minimum noise fraction (KMNF) transformation, which is a nonlinear ...

CMOS compatible metamaterial absorbers for hyperspectral medium wave infrared imaging and sensing applications [PDF]

open access: yes, 2018
We experimentally demonstrate a CMOS compatible medium wave infrared metal-insulator-metal (MIM) metamaterial absorber structure where for a single dielectric spacer thickness at least 93% absorption is attained for 10 separate bands centred at 3.08, 3 ...

Segmented Autoencoders for Unsupervised Embedded Hyperspectral Band Selection [PDF]

open access: yes2018 7th European Workshop on Visual Information Processing (EUVIP), 2018
One of the major challenges in hyperspectral imaging (HSI) is the selection of the most informative wavelengths within the vast amount of data in a hypercube. Band selection can reduce the amount of data and computational cost as well as counteracting the negative effects of redundant and erroneous information. In this paper, we propose an unsupervised,

Unsupervised Band Selection Method Based on Importance-Assisted Column Subset Selection

open access: yesIEEE Access, 2019
Band selection is an important preprocessing technique for hyperspectral images to select a band subset with representative information and low correlation. However, most methods focus on removing redundant components without loss of original information,

A survey of band selection techniques for hyperspectral image classification

open access: yesJournal of Spectral Imaging, 2020
Hyperspectral images usually contain hundreds of contiguous spectral bands, which can precisely discriminate the various spectrally similar classes. However, such high-dimensional data also contain highly correlated and irrelevant information, leading to

Unsupervised Cluster-Wise Hyperspectral Band Selection for Classification

open access: yesRemote Sensing, 2022
A hyperspectral image provides fine details about the scene under analysis, due to its multiple bands. However, the resulting high dimensionality in the feature space may render a classification task unreliable, mainly due to overfitting and the Hughes ...
