Line Plot from Scientific Research

CIEDE2000 difference between the references R and the simulation p(B*(LAB)) during the optimization. The left graph shows that on average the color difference is reduced in the first few iterations for each L* image and then remains constant, however for some colors the optimization later on reduces structural artifacts at the expense of the color accuracy. The right graph shows that computed over all colors in LAB also the maximal, median and 90th percentile difference in comparison to the references is reduced.
