  2. Image color transfer - Wikipedia

    en.wikipedia.org/wiki/Image_color_transfer

    The image modification process is sometimes called color transfer or, when grayscale images are involved, brightness transfer function (BTF); it may also be called photometric camera calibration or radiometric camera calibration. The term image color transfer is a bit of a misnomer since most common algorithms transfer both color and shading ...

  3. Opponent-process theory - Wikipedia

    en.wikipedia.org/wiki/Opponent-process_theory

    Opponent-process theory is a psychological and neurological model that accounts for a wide range of behaviors, including color vision. This model was first proposed in 1878 by Ewald Hering , a German physiologist, and later expanded by Richard Solomon , a 20th-century psychologist.

  4. Opponent process - Wikipedia

    en.wikipedia.org/wiki/Opponent_process

    The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels , each comprising an opposing color pair: red versus green , blue versus yellow ...

    RGB (red, green, blue) describes the chromaticity component of a given color, when excluding luminance. RGB itself is not a color space, it is a color model. There are many different color spaces that employ this color model to describe their chromaticities because the R/G/B chromaticities are one facet for reproducing color in CRT & LED displays.

Accounts may be associated with an identifier (account number) and a caption or header and are coded by ...

  9. Chrominance - Wikipedia

    en.wikipedia.org/wiki/Chrominance

    For example, when an ordinary RGB digital image is compressed via the JPEG standard, the RGB color space is first converted (by a rotation matrix) to a YCbCr color space, because the three components in that space have less correlation redundancy and because the chrominance components can then be subsampled by a factor of 2 or 4 to further ...
