What Differences Do Observers See In Colour Image Reproduction Experiments?

A large number of psychophysical experiments have been conducted in which observers judged the quality of reproduction either in terms of accuracy or pleasantness. However, all that these experiments say is how well a set of approaches that was used for reproducing some originals performs. What would be more important is to understand in what way the various colour reproduction methods fail so as to attempt an improvement in those areas. The aim of this paper is therefore to try to understand what factors contribute to judgements made by observers in experiments where they judge the quality of colour reproduction. Having an understanding of these then provides a new kind of basis for developing better colour image reproduction solutions. To this end the present paper describes the experimental method, data analysis and initial results of a psychophysical experiment where observers were asked to identify what differences they saw between a range of reproductions and their corresponding originals.

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.
