Colour difference metrics

In this research project, modern colour difference metrics [colour difference equations] are evaluated with a view to a better, i. e. perceptual uniform assessment of colour differences for typical graphic arts samples. For this purpose, to begin with, basics and usage tips for image appraisal for the practitioner have first been explained. Thereafter follows an account of the development of the different specifications for the calculation of colour difference. On the basis of different tests, developed in this research project, the different colour difference formulae are examined.

The extensive psychophysical data set established for this is now available.

The 8-page report is now available. Just look at the publication data base. For Fogra members this report is free of charge [immediate download from the publication database].
