Human color constancy in cast shadows [PDF]
i-PerceptionIllumination conditions inside and outside cast shadows typically differ significantly in both intensity and in chromaticity. However, our daily experiences suggest that we generally have no difficulty in stably perceiving surface color in cast shadows ...

Color Constancy via Multi-Scale Region-Weighed Network Guided by Semantics [PDF]
Frontiers in Neurorobotics, 2022 In obtaining color constancy, estimating the illumination of a scene is the most important task. However, due to unknown light sources and the influence of the external imaging environment, the estimated illumination is prone to color ambiguity.

Deep neural models for color classification and color constancy. [PDF]
J Vis, 2022 Color constancy is our ability to perceive constant colors across varying illuminations. Here, we trained deep neural networks to be color constant and evaluated their performance with varying cues.

Spectral Sharpening of Color Sensors: Diagonal Color Constancy and Beyond [PDF]
Sensors, 2014 It has now been 20 years since the seminal work by Finlayson et al. on the use of spectral sharpening of sensors to achieve diagonal color constancy. Spectral sharpening is still used today by numerous researchers for different goals unrelated to the ...

A Color-Opponency Based Biological Model for Color Constancy [PDF]
i-Perception, 2011 Color constancy is the ability of the human visual system to adaptively correct color-biased scenes under different illuminants. Most of the existing color constancy models are nonphysiologically plausible.

Impact of artificial intelligence-based color constancy on dermoscopical assessment of skin lesions: A comparative study. [PDF]
Skin Res Technol, 2023 The quality of dermoscopic images is affected by lighting conditions, operator experience, and device calibration. Color constancy algorithms reduce this variability by making images appear as if they were acquired under the same conditions, allowing ...

Three-Color Balancing for Color Constancy Correction [PDF]
Journal of Imaging, 2021 This paper presents a three-color balance adjustment for color constancy correction. White balancing is a typical adjustment for color constancy in an image, but there are still lighting effects on colors other than white. Cheng et al.

Color constancy mechanisms in virtual reality environments. [PDF]
J VisPrior research has demonstrated high levels of color constancy in real-world scenarios featuring single light sources, extensive fields of view, and prolonged adaptation periods. However, exploring the specific cues humans rely on becomes challenging, if

Color constancy in real-world settings. [PDF]
J VisColor constancy denotes the ability to assign a particular and stable color percept to an object, irrespective of its surroundings and illumination. The light reaching the eye confounds illumination and spectral reflectance of the object, making the ...

Color Constancy Using CNNs [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2015 In this work we describe a Convolutional Neural Network (CNN) to accurately predict the scene illumination. Taking image patches as input, the CNN works in the spatial domain without using hand-crafted features that are employed by most previous methods.
