Computing von Kries Illuminant Changes by Piecewise Inversion of Cumulative Color Histograms
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...

| Summary: | 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. We also propose a method for illuminant invariant image recognition based on
our von Kries transform estimate. |
