Radial Basis Function Neural Network for the Evaluation of Image Color Quality Shown on Liquid Crystal Displays

IEEE Access, 2021
The color quality of an image shown on a liquid crystal display (LCD) can be measured with a spectroradiometer; however, this instrument is expensive, work under controlled illumination conditions with an artificial source of light, and measurements take

Multiangle observations of Arctic clouds from FIRE ACE: June 3, 1998, case study [PDF]

, 2001
In May and June 1998 the Airborne Multiangle Imaging Spectroradiometer (AirMISR) participated in the FIRE Arctic Cloud Experiment (ACE). AirMISR is an airborne instrument for obtaining multiangle imagery similar to that of the satellite-borne MISR ...

Plant canopy shape and the influences on UV exposures to the canopy [PDF]

, 1996
The solar spectra at selected sites over hemispherical, conical and pinnacle plant canopy models has been evaluated with a dosimetric technique. The irradiance at the sites varies by up to a factor of 0.31 compared to the irradiance on a horizontal plane.

Proximal hyperspectral analysis in grape leaves for region and variety identification

Ciência Rural, 2023
: Reflectance measurements of plants of the same species can produce sets of data with differences between spectra, due to factors that can be external to the plant, like the environment where the plant grows, and to internal factors, for measurements of

The Use of Colorimeters to Support Remote Sensing Techniques on Asphalt Pavements

Remote Sensing, 2020
Characterization of asphalt pavements, based on ground spectroradiometers, has been studied in the past to determine their spectral response concerning the physical, chemical, and condition properties of the pavement.
