Perceptual Skin Tone Color Difference Measurement for Portrait Photography

In portrait photography, measuring the perceptual color differences (CDs) of skin tone is significant. Many studies have documented that the perception of skin tone is characteristically different from that of other colors. However, most existing CD measures are proposed based on psychophysical data...

Summary:In portrait photography, measuring the perceptual color differences (CDs) of skin tone is significant. Many studies have documented that the perception of skin tone is characteristically different from that of other colors. However, most existing CD measures are proposed based on psychophysical data of uniform color patches or natural images, and do not generalize well to the measurement of skin tone. In this paper, we construct the first large-scale portrait dataset for perceptual skin tone CD assessment and conduct psychophysical experiments to collect 160,000 perceptual CD judgments for 40,000 image triplets. Based on this dataset, we propose a deep skin tone CD measure for portrait photography. Extensive experiments demonstrate that our measure substantially outperforms existing CD measures on the problem of assessing skin tone CDs. The constructed dataset and code will be released to facilitate future research.
