Color Space
Color Space — A coordinate system for representing colour numerically; RGB, YCbCr and Lab serve different acquisition, coding and perceptual tasks.
Technical Context
A coordinate system for representing colour numerically; RGB, YCbCr and Lab serve different acquisition, coding and perceptual tasks.
The choice of colour space changes the meaning of distances and thresholds; a numerical distance in RGB does not carry the same interpretation as a perceptual distance in Lab.
