  2. Chromatic adaptation - Wikipedia

    en.wikipedia.org/wiki/Chromatic_adaptation

    Chromatic adaptation is the human visual system’s ability to adjust to changes in illumination in order to preserve the appearance of object colors. It is responsible for the stable appearance of object colors despite the wide variation of light which might be reflected from an object and observed by our eyes.

  3. Color appearance model - Wikipedia

    en.wikipedia.org/wiki/Color_appearance_model

    Chromatic adaptation is a prime example for the case that two different stimuli with thereby different XYZ tristimulus values create an identical color appearance. If the color temperature of the illuminating light source changes, so do the spectral power distribution and thereby the XYZ tristimulus values of the light reflected from the white ...

  4. CIECAM02 - Wikipedia

    en.wikipedia.org/wiki/CIECAM02

    The two major parts of the model are its chromatic adaptation transform, CIECAT02, and its equations for calculating mathematical correlates for the six technically defined dimensions of color appearance: brightness , lightness, colorfulness, chroma, saturation, and hue.

  5. Von Kries coefficient law - Wikipedia

    en.wikipedia.org/wiki/Von_Kries_coefficient_law

    One of the derivations of the von Kries coefficient law is the von Kries transform, a chromatic adaptation method that is sometimes used in camera image processing. Using the coefficient law, cone responses c ′ {\displaystyle c'} from two radiant spectra can be matched by appropriate choice of diagonal adaptation matrices D 1 and D 2 : [ 12 ]

  6. LMS color space - Wikipedia

    en.wikipedia.org/wiki/LMS_color_space

    The chromatic adaptation matrix in the diagonal von Kries transform method, however, operates on tristimulus values in the LMS color space. Since colors in most colorspaces can be transformed to the XYZ color space, only one additional transformation matrix is required for any color space to be adapted chromatically: to transform colors from ...

  7. Color vision - Wikipedia

    en.wikipedia.org/wiki/Color_vision

    In color science, chromatic adaptation is the estimation of the representation of an object under a different light source from the one in which it was recorded. A common application is to find a chromatic adaptation transform (CAT) that will make the recording of a neutral object appear neutral ( color balance ), while keeping other colors ...

  8. McCollough effect - Wikipedia

    en.wikipedia.org/wiki/McCollough_effect

    Neurophysiological explanations of the effect have variously pointed to the adaptation of cells in the lateral geniculate nucleus designed to correct for chromatic aberration of the eye, to adaptation of cells in the visual cortex jointly responsive to color and orientation (this was McCollough's explanation) such as monocular areas of cortical ...

  9. Color balance - Wikipedia

    en.wikipedia.org/wiki/Color_balance

    Color constancy is, in turn, related to chromatic adaptation. Conceptually, color balancing consists of two steps: first, determining the illuminant under which an image was captured; and second, scaling the components (e.g., R, G, and B) of the image or otherwise transforming the components so they conform to the viewing illuminant.
