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

Michela Lecca, Stefano Messelodi

• We present a linear algorithm for the computation of the illuminant change occurring between two colorpictures of a scene. We model the light variations with the von Kries diagonal transform and we estimate itby minimizing a dissimilarity measure between the piecewise inversions of the cumulative color histogramsof the considered images. We also propose a method for illuminant invariant image recognition based onour von Kries transform estimate.
