Evaluating the effect of noise on 3D LUT-based color transformations

摘要

Image reproduction suffers from several limitations in a color management system. In this paper, we have investigated artifacts resulting from the inherent characteristics of the color transformations by interpolation in three-dimensional look-up tables, and the unavoidable measurement noise of the color measurement done during device profiling. In our experiments, images were manipulated using three interpolation methods, and five levels of random noise. Psychophysical experiments were conducted to evaluate the quality of the reproduced images. Finally the experimental data were collected to analyze the color transformations, and test the performance of two color image difference metrics in this context.
