Stacked glass plates have discreetly accompanied the understanding of light since the origins of modern optics. They were studied by Bouguer, Lambert, Brewster, Arago, Stokes, Rayleigh, and many others, whose successive works progressively ...
Color constancy for daylight illumination changes in anomalous trichromats and dichromats [0.03%]
异常三色视者和二色视者的昼光照明变化色彩恒常性

Color constancy is the perceptual stability of surface colors under temporal changes in the illumination spectrum. The illumination discrimination task (IDT) reveals worse discrimination for "bluer" illumination changes in normal-trichromat...
Vortex X-wave propagation through von Kármán oceanic turbulence with anisotropy [0.03%]

Vortex X-waves with coupling effects of orbital angular momentum (OAM) and spatiotemporal invariance are introduced into the research of underwater wireless optical communication systems (UWOCSs). We establish the OAM probability density of...
Colorimetric characterization of the wide-color-gamut camera using the multilayer artificial neural network [0.03%]

Yasheng Li et al.
In order to realize colorimetric characterization for the wide-color-gamut camera, we propose using the multilayer artificial neural network (ML-ANN) with the error-backpropagation algorithm, to model the color conversion from the RGB space...
