Color Constancy is the ability to perceive colors of objects, invariant to the color of the light source. This ability is generally accredited to theHuman Visual System, although the exact details remain uncertain. An example of the ability is shown in the figure below. ...
1.3 什么是Color constancy? Color constancyis the ability torecognize colors of objects invariant(• adj. 不变的) of the color of the light source. Color constancy 是指【照片中物体的颜色】相对于【光源的颜色】,保持恒定不变。 如果发现【图片中物体的颜色】有失真,就需要通过特定的算法进行修正。那...
This paper presents detailed study of various color constancy techniques. Color constancy is the ability to estimate the color of the light source. Different illuminates may impact the appearance of an image as compared to the image taken under canonical light source. Human vision has the natural ...
Color constancy is the ability to measure colors of objects independent of the color of the light source. A well-known color constancy method is based on the gray-world assumption which assumes that the average reflectance of surfaces in the world is achromatic. In this paper, we propose a ...

Color Constancy is the ability of the human vision system to perceive the colors of the objects in the scene largely invariant to the color of the light source. The task of computational Color Constancy is to estimate the scene illumination and then perform the chromatic adaptation in order to...
(2011); after the training phase performed according to the above cited approaches, pixels are classified by a set of lookup tables, built using SVMs trained considering different features (i.e., different pre-processing and color spaces): The color constancy problem is the ability to estimate ...

The first definition states that color consistency is the ability to isolate the object reflectance from the surrounding illumination [3], [4], [5], whereas the second definition refers to the recovery of the object's chromatic appearance regardless the surrounding light source [6]. Even though...
