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 ...

Spectral-spatial multi-layer perceptron network for hyperspectral image land cover classification

open access: yesEuropean Journal of Remote Sensing, 2022
This paper proposes a novel spectral-spatial multi-layer perceptron network for hyperspectral image land cover classification. Current deep learning-based methods have limitations in spectral and spatial feature representation of hyperspectral images ...

Combining multiscale features for classification of hyperspectral images: a sequence based kernel approach [PDF]

open access: yes, 2016
Nowadays, hyperspectral image classification widely copes with spatial information to improve accuracy. One of the most popular way to integrate such information is to extract hierarchical features from a multiscale segmentation.

Advances in Hyperspectral Image Classification: Earth monitoring with statistical learning methods [PDF]

open access: yes, 2013
Hyperspectral images show similar statistical properties to natural grayscale or color photographic images. However, the classification of hyperspectral images is more challenging because of the very high dimensionality of the pixels and the small number

STACKED LOCAL FEATURE DETECTOR FOR HYPERSPECTRAL IMAGE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Images registration is an important task in hyperspectral image processing, while almost all local feature point based image matching algorithm is designed for single band image only and miss the advantage of abundant spectral information.
