Abstract

This research presents a novel colour management system within an Image Signal Processor pipeline that encompasses the colour constancy problem and reproduces perceptually pleasing colours in the final image produced by an ISP. The proposed colour management system includes a new machine learning based automatic white balancing algorithm, an intelligent colour matrix balancing method for achieving colour constancy in non-orthogonal camera colour functions and a cooling-warming approach based on Kruithof curve to achieve pleasing colours in the final image produced by the ISP.
