Color by Numbers - Quantifying the Quality of Color Reproduction

Quantifying the perceptual difference between original and reproduced (and inevitably modified) color images is currently a key research challenge in the field of color imaging. Such information can be extremely valuable for instance in the development of new equipment and algorithms for color reproduction. While in many research areas it is common practice to obtain quantitative quality inform...

Color Reproduction Algorithms and Intent

The effect of image type on systematic differences from strict colorimetric reproduction is investigated and discussed. Different situations, called “color intents,” are described. We have identified four basic color intents. Color reproduction algorithms for each intent are presented, together with guidelines for selecting the appropriate intent.

Color Correction for Tone Reproduction

High dynamic range images require tone reproduction to match the range of values to the capabilities of the display. For computational reasons as well as absence of fully calibrated imagery, rudimentary color reproduction is often added as a postprocessing step rather than integrated into the tone reproduction algorithm. However, in the general case this currently requires manual parameter tuni...

Spectral Color Reproduction of Paintings

A spectral-based imaging system was constructed consisting of a two-sequential-absorption-filter-CFA digital camera and a seven-color inkjet printer and used to image and print a post-impressionist style painting such that matches were generated for CIE Illuminants D65 and A. Camera calibration was learning based using the Matrix R method. Rendered images for both illuminants were inputted to a...
