S-CIELAB:
A Spatial Extension to the CIE Lab* DeltaE Color Difference Metric

S-CIELAB is an extension of the CIE L*a*b* DeltaE color difference formula. The extension is in the form of a spatial pre-processing step that incorporates the pattern-color sensitivity measurements by Allen Poirson and Brian Wandell . For more details, please see below.
