Color Constancy Using a Global Nose Camera Attachment
In this paper, the previous system is modified by reducing the nose size which becomes suitable for measuring uniform illumination color in the scene. In the modified system, the nose image appears continually as a small triangle in an image corner occupying less than 3% of the image area. The color correction algorithm processes the saturated pixels to give them a natural appearance.
A novel technique to balance image colors optically is also introduced that preserves the color resolution in the corrected image. Extensive experiments were carried out which confirmed the effectiveness of the new system.

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.
