Color image quality metric S-CIELAB and its application on halftone texture visibility
Proceedings IEEE COMPCON 97. Digest of Papers
We describe experimental tests of a spatial extension to the CIELAB color metric for measuring color reproduction errors of digital images. The standard CIELAB AE metric is suitable for use on large uniform color targets, but not on images, because color sensitiviq changes as a function of spatial pattern. The S-CIELAB extension includes a spatial processing step, prior to the CIELAB AE calculation, so that the results correspond better to color difference perception by the human eye.
