A Quantitative Parameter of Nonlinear Tone Compression for HDR Color Reproduction

摘要

High-dynamic-range (HDR) images were embodied by a lot of algorithms. This paper takes notice one of these algorithms, which is iCAM06. iCAM06 has worked color appearance prediction of HDR images based on CIECAM02 color prediction and incorporates the spatial processing models in the human vision system for contrast enhancement. We investigated the effect of user controllable factors of iCAM06 and tried to find the best factor which is correspondence with Breneman's corresponding color data sets. Suggested model meet with good results, it improves color matching prediction for corresponding color data set in Breneman's experiment.
