The use of large displays for purposes of colour communication is becoming increasingly popular and the need for high-fidelity reproduction of appearance is becoming even more demanding. In this work, the colour appearance of the ColorChecker chart was matched on a large liquid crystal display (LCD) and a comparison between the physical colours and the displayed image was made. Colour definition and colour perception spaces were used to derive appearance models that define the difference between the digital and physical stimuli. The procedure was repeated using a selection of coloured garments as stimuli. The results revealed a good agreement in the defining the appearance difference between digital and physical stimuli. In both cases the difference in lightness between the two media was found to be responsible for the variation in matching. This outcome was used to develop a colour-rendering chain for the display. The use of appearance modelling in the digital image reproduction chain enhanced the appearance of solid paint-coated surfaces and dyed-garment images.

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.
