Abstract
A reference value for a color statistic and an input image sample are received. A global color mapping is performed between the input image sample and the reference value to obtain a globally-mapped input image sample, the color statistic of the globally-mapped input image sample substantially matching the reference value and each pixel location in the globally-mapped input image sample having a correspondence with a corresponding pixel location in the input image sample. A point-to-point color mapping function minimizing for all pixels an error between the globally-mapped input image sample and the input image sample mapped according to the color mapping function is computed, the color mapping function transforming a color value of each pixel location in the input image sample to substantially match a color value of the corresponding pixel location in the globally-mapped input image sample.
