Quantifying Smoothness of the LUTs-based Color Transformations
The quality of reproduced images suffers from several limitations in a color management system, such as device profiling, color transformation, etc. one of the most accurate numerical models for device profiling is achieved by the measurement of a large number of colors which, in turn, can be used to develop multi-dimensional look-up-tables (LUTs) with interpolation for any intermediate colors. To achieve high quality on image reproduction and acceptable performance of a color management system, relative smooth color transformation using LUTs is demanded. A research was carried out to explore the possibility to measure the smoothness of LUT transformation in the color management system based on ICC specifications. Psychophysical experiments were conducted to evaluate the smoothness of the reproduced images subjectively by using a number of ICC printer profiles. An image difference metric was designed and tested to quantify the experimental results objectively.
