one illuminant but different under another, were obtained from 50 hyperspectral images of …

Color constancy in natural scenes explained by global image statistics

DH Foster, K Amano, SMC Nascimento - Visual neuroscience, 2006 - cambridge.org
To what extent do observers' judgments of surface color with natural scenes depend on
global image statistics? To address this question, a psychophysical experiment was …

Discrimination of amplitude spectrum slope in the fovea and parafovea and the local amplitude distributions of natural scene imagery

BC Hansen, RF Hess - Journal of vision, 2006 - jov.arvojournals.org
A number of studies have investigated whether human visual performance can be related to
the general form of the amplitude spectra (ie, 1/f α) of natural scenes. Here, it is argued that …

Image statistics of American Sign Language: comparison with faces and natural scenes
