However, low signal-to-noise ratios (SNR) due to low water-leaving radiance combined with environmental variability make it very difficult to design an optimal processing algorithm.
Here, we selected a state-of-the-art, forward semi-analytical model in which we included a mixing model of four seabed albedo, namely sand, corals, algae and seagrass.
One of the biggest technical challenges for field phenotyping of grapevines are the varying light conditions and the background.
In the present study the Phenoliner is presented, which represents a novel type of a robust field phenotyping platform.
Several absorption features, including six narrow absorption peaks at 425 nm, 1480 nm, 2160 nm, 2218 nm, 2253 nm, and 2347 nm, and three wide peaks between 625â€“756 nm, 756â€“915 nm, and 1885â€“2133 nm have been identified.
The strength of the absorption of turquoise increased with decreasing hardness.
The results on our study areas clearly highlighted the interest of relaxing the ASC when the bottom depth is shallow.
In deeper areas, ASC versions of LS- and LSD-based inversion setups produced the best seabed type mapping results.
RASC-LSD also produced the most accurate results in terms of spatial coverage of benthic components on a very shallow area (inner part of a fringing reef).The absorption peaks at 2160 nm, 2218 nm, 2253 nm, 2347 nm, and 1885â€“2133 nm on some turquoise spectra (porcelain spectra, for example) were relatively weak, while those at 425 nm, 1480 nm, 625â€“756 nm, and 756â€“915 nm were always observed on all turquoise spectra, which could be the diagnostic absorption features for turquoise.
