Nature-Inspired Framework for Hyperspectral Band Selection
(Institute of Electrical and Electronics Engineers (IEEE), 2014-04-01)
Although hyperspectral images acquired by on-board satellites provide information from a wide range of wavelengths in the spectrum, the obtained information is usually highly correlated. This paper proposes a novel framework ...
A robust stochastic approach to mineral hyperspectral analysis for geometallurgy
(MDPI, 2020)
Most mining companies have registered important amounts of drill core composite spectra
using different acquisition equipment and by following diverse protocols. These companies have
used classic spectrography based on ...
Impact of reduction of radiometric resolution in hyperspectral images acquired over forest field
(2018-09-20)
The objective of this study was to evaluate the impact of reducing the radiometric information of hyperspectral images. The image data was collected originally with 32 bits and rescaled to 8 and 16 bit/pixel. The images ...
Rock lithological classification by hyperspectral, range 3D and color images
(Elsevier B.V., 2019)
Mine operations in the future will require automatic rock characterization at many different stages, since it can be used to supervise and optimize various processes in the laboratory as well as at the mine locations for ...
Dimensionality reduction via an orthogonal autoencoder approach for hyperspectral image classification
(The International Society for Photogrammetry and Remote SensingDE, 2020)
Nowadays, the increasing amount of information provided by hyperspectral sensors requires optimal solutions to ease the subsequent analysis of the produced data. A common issue in this matter relates to the hyperspectral ...
Exterior orientation of hyperspectral frame images collected with UAV for forest applications
(2016-03-17)
This paper describes a preliminary study on the image orientation acquired by a hyperspectral frame camera for applications in small tropical forest areas with dense vegetation. Since access to the interior of forests is ...
