The present invention relates to a method and system and computer program product for deriving a new index sequence representing a pixel mapping and a new output function representing a colour palette applying a soft decision optimization process to a new digitized colour image derived from an original digitized colour image both defined on n pixels, wherein the original digitized colour image is provided by N distinct colours being allocated to the n pixels, the new digitized colour image is provided by M distinct colours being allocated to the n pixels, the new index sequence has n index members for representing the n pixels and the new output function is for mapping the n index members to the M colours. |
