Lab Channel

The Lab Channel module provides a way to convert to and from the CIE-L*ab color space. The Lab color space converts a pixels light into the L channel with a and b being color channels.

L - The L dimension of the Lab color space
a - The a dimension of the Lab color space
b - The b dimension of the Lab color space
Lab as RGB - convert the current image into Lab color space and apply each of the Lab channels into the RGB channels
RGB as Lab - convert from Lab space into RGB space by assuming that the current RGB image includes Lab color space data.
