Abstract

Colour clustering (or colour quantisation) is an elementary image processing process to reduce the number of distinct colours in an image. Colour quantised images contain a colour palette and it is the entries in this palette that determine the quality of the resulting image. Colour quantisation is known to be a problem that is NP-complete, and therefore effective and efficient methods of deriving good colour palettes are sought. In this paper, we present several computational intelligence methods for colour quantisation.
