Towards a New Colour Appearance Model for Self-luminous Stimuli
(Illuminating Engineering Institute of Japan, 2017-03)
Based on the experimental visual data obtained for self-luminous stimuli surrounded by a dark background,a new colour appearance model (CAM) for unrelated self-luminous stimuli, CAM15u, was previouslydeveloped. To extend ...
Differential predation by mammals and birds: Implications for egg-colour polymorphism in a nomadic breeding seabird
(Oxford University Press, 2002-02)
Selection for crypsis in varying environments has long been established as the main evolutionary force promoting the huge variation in avian egg coloration. In several avian species, variation in egg coloration exists, but ...
Chromatic variability and sexual dimorphism in the rocky lizard phymaturus verdugo
(National Research Council Canada-NRC Research Press, 2018-06)
The genus Phymaturus comprises lizards that inhabit cold environments at high altitudes or latitudes. Phymaturus verdugo Cei and Videla, 2003 is characterized by cephalic melanism, which is interpreted as a character present ...
Variation in multicomponent recognition cues alters egg rejection decisions: A test of the optimal acceptance threshold hypothesis
(The Royal Society, 2019-04)
The optimal acceptance threshold hypothesis provides a general predictive framework for testing behavioural responses to discrimination challenges. Decision-makers should respond to a stimulus when the perceived difference ...
Analysis from avian visual perspective reveals plumage colour differences among females of capuchino seedeaters (Sporophila)
(Wiley Blackwell Publishing, Inc, 2010-11)
Females of the closely related capuchino seedeaters are difficult to distinguish from one another based on human visual perception of colouration and morphology. We examined plumage colour differences among females of four ...
Luminance distribution modifies the perceived freshness of strawberries.
(SAGE Publications, 2012-05-12)
Material perception studies focus on the analysis of visual cues that may underlie the ability to distinguish between the different properties of an object. Herein, we investigated the effects of luminance distribution on ...
Foveal spatial summation in human cone mechanism
(Pion Ltd, 2011-08)
We measured at the fovea the chromatic contrast threshold for stimuli modulated along different chromatic directions in the isoluminant plane of MBDKL colour space, considering the two cardinal axes (L+M) and S/(L+M) and ...
Percepción del color: una respuesta conceptualista a la crítica de circularidadPerception of colours: a conceptualist response to the circularity criticisms
(Universidad de Málaga, 2018-04)
En este trabajo se ofrece una respuesta conceptualista a la crítica de circularidad en la adquisición y posesión de conceptos observacionales, esgrimida por Peacocke. Tal respuesta consiste en proponer un proceso de ...
