Abstract
One or more versions of video or other image content may be generated by obtaining first histogram data for a first version of the video content; obtaining a second version of the video content; obtaining second histogram data for the second version of the video content; generating a mapping from the second version of the video content to an additional version of the video content by performing a number of iterations of a progressive histogram matching algorithm, the number of iterations being fewer than a maximum number of iterations of the progressive histogram matching algorithm; and applying the mapping to generate the additional version of the video content from the second version of the video content.
