Validation of a New Digital and Automated Color Perception Test
DiagnosticsAlthough color vision deficiencies are very prevalent, there are no ideal methods for assessing color vision in all environments. We compared a new digital and automated method that quantifies color perception for the three protan, deutan, and tritan ...

Illuminant cues in surface color perception: tests of three candidate cues
Vision Research, 2001 Many recent computational models of surface color perception presuppose information about illumination in scenes. The models differ primarily in the physical process each makes use of as a cue to the illuminant. We evaluated whether the human visual system makes use of any of three of the following candidate illuminant cues: (1) specular highlight, (2)

Generalization of color by chickens: experimental observations and a Bayesian model [PDF]
, 2007 Sensory generalization influences animals' responses to novel stimuli. Because color forms a perceptual continuum, it is a good subject for studying generalization. Moreover, because different causes of variation in spectral signals, such as pigmentation,
