We have developed a model to calculate chromaticity difference from a surface defined from the MacAdam ellipses in CIE 1931 (x,y)-chromaticity diagram. The idea is to tranform the MacAdam ellipses to circles on a surface. The height of the surface is obtained by projecting a circle of constant radius such that the projection is equal to the ellipse on the the (x,y)-plane. The chromaticity difference is calculated from the surface by a method based on the Weighted Distance Transform On Curved Space (WDTOCS).

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
