17 p, 370.5 KB Computing von Kries Illuminant Changes by Piecewise Inversion of Cumulative Color Histograms / Lecca, Michela (Fondazione Bruno Kessler. Center for Scientific and Technological Research (Trento, Itàlia)) ; Messelodi, Stefano (Fondazione Bruno Kessler. Center for Scientific and Technological Research (Trento, Itàlia))
We present a linear algorithm for the computation of the illuminant change occurring between two color pictures of a scene. We model the light variations with the von Kries diagonal transform and we estimate it by minimizing a dissimilarity measure between the piecewise inversions of the cumulative color histograms of the considered images.
