R 2 pixxel from 0. Image and Video Processing Articles Cited by Co-authors. August 21, Published: We show that there exists a single invariant color coordinate, a function of RGand Bthat depends only on surface reflectance.

Color constancy at a pixel.

See our FAQ piel additional information. Consequently, modern color constancy algorithms attempt only to recover image chromaticities under the reference light: In recent years almost all authors have argued that this three-dimensional problem is too hard. Share buttons are a little bit lower. New articles by this author.

Color constancy for scenes with varying illumination K Barnard, G Finlayson, B Funt Computer vision and image understanding 65 2, Kodak DCS camera is much less sharp. Mechanisms of color constancy M. Consequently, modern color constancy algorithms attempt only to recover image chromaticities under the reference light: We ask, Is there a single color coordinate, a function of image chromaticities, for which the color constancy problem can be solved?

Our answer is an emphatic yes. International Journal of Computer Vision 85 1, Peter Morovic HP Inc. In computational terms we can solve the color constancy problem if device red, green, and blue sensor responses, or RGB’s, for surfaces seen under an unknown illuminant can be mapped to corresponding RGB’s under a known reference light.

First, given an RGB image of a scene viewed under any illuminant, we can trivially synthesize the same gray-scale image we simply code the invariant coordinate as a gray scale.

August 21, Manuscript Accepted: While significant progress has been made toward achieving chromaticity constancy, recent work has shown that the most advanced algorithms are unable to render chromaticity stable enough so that it can be used as a cue for object recognition [B.
