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 colour mapping model from a set of tuples of corresponding colours relative to at least two images. The method is characterised in that it uses processing means for: - selecting at least one intermediate tuple of corresponding colours from the set of tuples of corresponding colours by using at least one channel-wise colour mapping model, and - estimating said at least one cross-channel colour mapping model from said at least one intermediate selected tuple of corresponding colours.
