Heliyon, 2022 To extract blue roofs (BRs) from remote sensing images quickly, first, this study used WorldView-2 and WorldView-3 as the data sources and created a new BR spectral area model (BRSAM) using the polygon area difference between the spectral curves of BRs ...

A Spectral Model of Turnover Reduction [PDF]
Econometrics, 2015 We give a simple explicit formula for turnover reduction when a large number of alphas are traded on the same execution platform and trades are crossed internally. We model turnover reduction via alpha correlations. Then, for a large number of alphas, turnover reduction is related to the largest eigenvalue and the corresponding eigenvector of the alpha

Non-destructive monitoring of amylose content in rice by UAV-based hyperspectral images
Frontiers in Plant Science, 2022 Amylose content (AC) is an important indicator for rice quality grading. The rapid development of unmanned aerial vehicle (UAV) technology provides rich spectral and spatial information on observed objects, making non-destructive monitoring of crop ...

Spectral-based printer modeling and characterization [PDF]
Journal of Electronic Imaging, 2005 Spectral characterization involves building a model that relates the device dependent representation to the reflectance func- tion of the printed color, usually represented with a high number of reflectance samples at different wavelengths. Look-up table-based approaches, conventionally employed for colorimetric device char- acterization cannot be ...

A predictive model for the spectral “bioalbedo” of snow [PDF]
Journal of Geophysical Research: Earth Surface, 2017 AbstractWe present the first physical model for the spectral “bioalbedo” of snow, which predicts the spectral reflectance of snowpacks contaminated with variable concentrations of red snow algae with varying diameters and pigment concentrations and then estimates the effect of the algae on snowmelt.

A spectral model for multimodal redshift estimation [PDF]
2016 IEEE Symposium Series on Computational Intelligence (SSCI), 2016 We present a physically inspired model for the problem of redshift estimation. Typically, redshift estimation has been treated as a regression problem that takes as input magnitudes and maps them to a single target redshift. In this work we acknowledge the fact that observed magnitudes may actually admit multiple plausible redshifts, i.e.
