Associating color appearance with the cone chromaticity space
A cone chromaticity space, a transform of a colorimetric specification system into coordinates that represent cone excitations, does not provide color appearance information. Boynton and Olson (Color Research and Application 12, 94-105, 1987) gathered color naming for the 424 Optical Society of America Uniform Color Scales (OSA-UCS) color samples. Here, a computational algorithm was developed t...
متن کاملColor constancy through inverse-intensity chromaticity space.
Existing color constancy methods cannot handle both uniformly colored surfaces and highly textured surfaces in a single integrated framework. Statistics-based methods require many surface colors and become error prone when there are only a few surface colors. In contrast, dichromatic-based methods can successfully handle uniformly colored surfaces but cannot be applied to highly textured surfac...
متن کاملColor space distortions in patients with type 2 diabetes mellitus.
Color vision impairment was examined in patients with type 2 diabetes mellitus (DM2) without retinopathy. We assessed the type and degree of distortions of individual color spaces. DM2 patients (n = 32), and age-matched controls (n = 20) were tested using the Farnsworth D-15 and the Lanthony D-15d tests. In addition, subsets of caps from both tests were employed in a triadic procedure (Bimler &...
متن کاملColor constancy by chromaticity neutralization.
In this paper, a robust illuminant estimation algorithm for color constancy is proposed. Considering the drawback of the well-known max-RGB algorithm, which regards only pixels with the maximum image intensities, we explore the representative pixels from an image for illuminant estimation: The representative pixels are determined via the intensity bounds corresponding to a certain percentage va...
متن کاملNeural modelling of the McCollough Effect in color vision
The present work investigates the neural mechanisms underlying the McCollough Effect through the simulation of three different models of color visual systems: a dichromatic and a trichromatic one that are inspired to the anatomy of the primates’ visual system and an idealised trichromatic model designed to aid the self-organization of a simulated Primary Visual Cortex to a physiologically-plaus...
