The Advanced Geosynchronous Radiation Imager (AGRI) has 14 spectral bands
(increased from the five bands of FY-2) that are quantized with 12 bits per pixel (up from 10 bits for FY-2) and sampled at 1 km at nadir in the visible (VIS), 2 km in the near-infrared (NIR), and 4 km in the remaining IR spectral bands
(compared with 1.
This data cube corresponds to a hyperspectral image with 8 spectral bands
Table 2 shows the calculated attenuation coefficients ratios (ki/kj) for each pair of spectral bands
i] is the mean radiance of each spectral band
involved in the fusion,
Processed image visualized from the spectral bands
similarly to human perception is presented in Fig.
Both the position and the width of relevant spectral bands
should be identified.
Hyperspectral imaging sensor can obtain simultaneously image and spectroscopy in a single scanning process, which usually comprises about hundreds of spectral bands
of relatively narrow bandwidths as well as high spatial resolution images.
A lot of minerals were classified into incorrect classes because of considerable variability of spectral bands
Landsat TM images have a spatial resolution of 30 m and 7 spectral bands
The power represented by various spectral bands
in short-term HRV are indicative of how well the heart responds to changes in the body controlled by the sympathetic and the parasympathetic nervous systems.
Further units are planned for near-UV wavelengths between 385 and 390 nm, power above 5W and multi-watt pulsed and CW fiber lasers for green and blue spectral bands
It was due to high level of cross-channel correlations among spectral bands
In their research, the scientists choose a few optimal spectral bands
from many that will get the job done with enough speed and accuracy when used in multispectral imaging systems.
Reflectance spectra of three different classes of fungal infected leaves were measured using GER1500 Spectroradiometer for 512 spectral bands
from 305 nm to 1089 nm.
That's done by looking at a combination of spectral bands
relating to the infrared response of chlorophyll absorption and reflectance.
