Color 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 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 کاملChromaticity limits in color constancy calculations
There are two very different kinds of color constancy. One kind studies the ability of humans to be insensitive to the spectral composition of scene illumination. The second studies computer vision techniques for calculating the surface reflectances of objects in variable illumination. Camera-measured chromaticity has been used as a tool in computer vision scene analysis. This paper measures th...
متن کاملColor constancy: the role of image surfaces in illuminant adjustment
Previous studies on color constancy have found that the color appearance of a test surface varies both as a function of the illumination in the image and as a function of the image surfaces. To what extent these two effects interact is investigated here. To address this issue theoretically, a restrictive von Kries model is formulated that assumes that the scaling of the cone signals in response...
متن کاملColor Constancy by Learning to Predict Chromaticity from Luminance
Color constancy is the recovery of true surface color from observed color, and requires estimating the chromaticity of scene illumination to correct for the bias it induces. In this paper, we show that the per-pixel color statistics of natural scenes—without any spatial or semantic context—can by themselves be a powerful cue for color constancy. Specifically, we describe an illuminant estimatio...
