A Modified Color Appearance Model of CIELAB

Abstract

A new controllable color appearance model (CAM) called QLAB is presented based on CIELAB. QLAB is derived from the perceptually uniform CIELAB color model, and is provided with perceptual representation way extracted from HSB color model. The QLAB offers a regular form and perceptual uniformity color model to designers. The process and methods of constructing QLAB is described, and two application cases are discussed at last. The test results show that QLAB is more controllable and practical than general CAMs. A new controllable color appearance model (CAM) called QLAB is presented based on CIELAB.
