An Evaluation of Significant Lightness Difference Effective Term for CIEDE2000 Comparative Image Colour Pixels

ECTI Transactions on Computer and Information Technology (ECTI-CIT), 1970
As CIEDE2000 standard has developed the colour difference formula, the colour difference formula of compared colours in similar colour space has been evaluated and emphasized in this paper. The lightness difference effective term has been distinctively separated from the small informative colourdifference of CIEDE2000.

Calculating Spectral Color Difference

, 2013
Olemassa olevat spektrieromittarit eivät vastaa riittävästi CIEDE2000-värieroa. Tämän työn tavoitteena oli toteuttaa menetelmä, joka laskee värispektrien eron siten, että tulos vastaa CIEDE2000-värieroa.
