METHOD AND ARRANGEMENT FOR ESTIMATING AT LEAST ONE CROSS-CHANNEL COLOUR MAPPING MODEL FROM AN SET OF TUPLES OF CORRESPONDING COLOURS RELATIVE TO AT LEAST TWO IMAGES

摘要

The present invention generally relates to a method and arrangement for estimating said at least one cross-channel color mapping model from a set of tuples of corresponding colors relative to at least two images. The method is characterized in that it uses a processor for selecting at least one intermediate tuple of corresponding colors from the set of tuples of corresponding colors by using at least one channel-wise color mapping model, and for estimating the at least one cross-channel color mapping model from the at least one intermediate selected tuple of corresponding colors.
