Abstract:
In this work we are investigating ICC color management workflow in color imaging system and proposing improvement to standard ICC-based color management scheme. We are created optimal look-up tables of ICC profiles by using spline approximation and neural network for direct transformation RGB → Lab and regression models for inverse transformation Lab → RGB and integrated criterion (optimization criterion). Our algorithm implements corresponding color reproduction to accurately predict memorable and scene-important colors. Mean errors was reduced by 21% as compared to standard color profiles for particular output device and type of paper.
