Illumination Color and Intrinsic Surface Properties – Physics - Based Color Analyses from a Single Image –
A consistent color descriptor of an object is a significant requirement for many applications in computer vision. In the real world, unfortunately, the color appearances of objects are generally not consistent. It depends principally on two factors: illumination spectral power distribution (illumination color) and intrinsic surface properties. Consequently, to obtain objects’ consistent color d...
متن کاملColor constancy: surface color from changing illumination
Received September 5, 1991; revised manuscript received October 30, 1991; accepted November 13, 1991 Viewing the lights reflected by a set of three or more surfaces, a trichromatic visual system can recover three color-constant descriptors of reflectance per surface if the color of the surfaces' illuminant changes. This holds true for a broad range of models that relate photoreceptor, surface, ...
متن کاملRobust Estimation of Surface Color from Single Image Using Illumination Variance
Color appearance of an object varies due to the color of the illumination. To arrive at color constancy, we have developed a physics-based method of estimating surface colors and removing the illumination colors by utilizing illumination variance. In this paper, we focus on the use of this method to deal with outdoor scenes, since very few physics-based methods have successfully handled outdoor...
متن کاملIllumination-Invariant Color Image Correction
This paper presents a new statistical approach for learning automatic color image correction. The goal is to parameterize color independently of illumination and to correct color for changes of illumination. This is useful in many image processing applications, such as color image segmentation or background subtraction. The motivation for using a learning approach is to deal with changes of lig...
متن کاملSurface color perception and equivalent illumination models.
Vision provides information about the properties and identity of objects. The ease with which we perceive object properties belies the difficulty of the underlying information-processing task. In the case of object color, retinal information about object reflectance is confounded with information about the illumination as well as about the object's shape and pose. There is no obvious rule that ...
