The Evaluation of Lightness and Chroma Difference for Images According to Color Difference Formulae
The computation and evaluation of color difference for images is a hot topic. In order to explore the calculation method of evaluating color difference sensation for similar images, 68 pairs of test images were made, which were made from ISO SCID 400 color images by altering their lightness and chroma respectively to cause different color difference scales, and tested by psychophysical experiment. The experiment results showed that the calculated color difference by each formula had a relation to the color difference sensation and the color difference formulae were optimized based on the experimental data.
