Color Tone of Various Melanoidins Produced from Model Systems

Color correction for tone mapping

Tone mapping algorithms offer sophisticated methods for mapping a real-world luminance range to the luminance range of the output medium but they often cause changes in color appearance. In this work we conduct a series of subjective appearance matching experiments to measure the change in image colorfulness after contrast compression and enhancement. The results indicate that the relation betw...

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...

3D Face Reconstruction from Single Two-Tone and Color Images

This chapter addresses the problem of reconstructing the three-dimensional shape of faces from single images. We present an algorithm that uses prior knowledge of faces—a single shape model of a face—to eliminate the ambiguities in the reconstruction [13, 14]. The algorithm achieves veridical reconstruction results on images taken under a wide range of viewing conditions. In addition, it can re...

Estimation of dietary intake of melanoidins from coffee and bread.

Melanoidins are defined as polymeric high molecular weight, brown-coloured Maillard reaction end-products, containing nitrogen. They escape digestion and pass through the upper gastrointestinal tract and can interact with the different microbial species present in the colon. Major dietary sources of melanoidins are coffee and bread crust. Both coffee and bread crust melanoidins can be fermented...
