Color vision deficiency is the decreased ability to perceive color differences. To overcome this deficiency, supporting techniques for realizing barrier-free color environments are required. This paper proposes a color appearance control system to enable people afflicted with color vision deficiency to easily distinguish between confusing colors on any printed images using a projector-camera system. The proposed system captures a printed image using a video camera and shifts the lightness components of each pixel by super-imposing a compensation image obtained from the projector device onto the printed image. The compensation image is produced in the CIEL*a*b* color space for iteratively adjusting the desired lightness components toward the target lightness. The feasibility of the proposed system is verified experimentally using real printed 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.
