Image comparison measure for digital still color cameras

摘要

A measure is developed for comparing complex scenes produced by single-chip digital color cameras. The proposed measure is based on the CIELAB color space with appropriate considerations to the sensitivity of the human visual system (HVS) when viewing a complex scene. For comparison purposes, the error measures proposed have been implemented using the /spl Delta/E/sub ab//sup */, /spl Delta/E/sub 94//sup */ and the recently recommended CIEDE2000 color differences.
