Improvement of leaf nitrogen content inference in Valencia-orange trees applying spectral analysis algorithms in UAV mounted-sensor images
(Elsevier B.V., 2019-11-01)
Nitrogen is one of the main required nutrients for the production of citrus plants. Farmers have used the chemical analysis of leaf tissue to determine the amount of nitrogen needed in a crop. However, its possible to ...
A study on the effects of viewing angle variation in sugarcane radiometric measuresEstudo do efeito da variação no ângulo de visada em medidas radiométricas na cana-de-açúcar
(2018-01-01)
Remote Sensing techniques, such as field spectroscopy provide information with a large level of detail about spectral characteristics of plants enabling the monitoring of crops. The aim of this study is to analyze the ...
Scaling dimensions in spectroscopy of soil and vegetation

Controller Design Based on Spectral Sensors for Process Applications
(2014)
Multidimensional sensors such as spectral sensors
have been widely used in monitoring tasks. They provide
simultaneously many measurements distributed over the spectra.
These measurements are normally highly correlated ...
Shadow detection in hyperspectral images acquired by uav
(2019-06-04)
Shadows are common in any kind of remote sensing images. Unmanned Aerial Vehicle – UAV with a light camera attached can acquire images illuminated either by direct sunlight or by diffuse light under clouds. Indeed, ...

Sparse representations of dynamic scenes for compressive spectral video sensing
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
The coded aperture snapshot spectral imager (CASSI) is an optical architecture that captures spectral images using compressive sensing. This system improves the sensing speed and reduces the large amount of collected data ...
ASSESSMENT OF FAST SPECTRAL WAVE TRANSFER METHODOLOGIES FROM DEEP TO SHALLOW WATERS IN THE FRAMEWORK OF ENERGY RESOURCE QUANTIFICATION IN THE CHILEAN COAST
(2014)
Alternative wave transfer methodologies from deep to shallow water that aim at reducing the computational time in cases where the full propagation of a large number of wave climates is often prohibitive are defined and ...
