Combination of Clustering and Ranking Techniques for Unsupervised Band Selection of Hyperspectral Images

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
Curse of dimensionality is a major disadvantage for classification of hyperspectral imagery since a large number of bands need to be dealt with. Band selection is a task to reduce the number of bands. An unsupervised band selection method is proposed in this article. It is a three-step procedure.

Fractal Autoencoder-Based Unsupervised Hyperspectral Bands Selection for Remote Sensing Land-Cover Classification

open access: yesEngineering Proceedings, 2023
Band selection is a frequently used dimension reduction technique for hyperspectral images (HSI) to address the “curse of dimensionality” phenomenon in machine learning (ML). This technique identifies and selects a subset of the most important bands from

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,

Robust Unsupervised Hyperspectral Band Selection via Global Affinity Matrix Reconstruction

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Unsupervised band selection is fundamental to alleviate the curse of dimensionality for hyperspectral imagery. Although many research works have been developed, it is still a challenging problem to improve the poor classification performance with a small

Unsupervised hyperspectral band selection using parallel processing [PDF]

open access: yes2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Band selection is a common technique to reducing the data dimensionality of hyperspectral imagery. When the desired object information is unknown, the objective of an unsupervised band selection approach is to select the most distinctive and informative bands. Although band selection can significantly alleviate the computational burden in the following

Band Ranking via Extended Coefficient of Variation for Hyperspectral Band Selection

open access: yesRemote Sensing, 2020
Hundreds of narrow bands over a continuous spectral range make hyperspectral imagery rich in information about objects, while at the same time causing the neighboring bands to be highly correlated.
