Yuchun Yan is now a master of science! She submitted the thesis, entitled “Skin Balancing: Chromatic Adjustment of Multi-illuminant Portraits on One Scene using Facial Color to Reproduce Standard Image Quality”. She investigated the special situation when multiple portraits undue different scene illuminants gathered together and how people perceive the color difference in terms of content bias. A method named ‘Skin Balancing’ was also proposed to standardize multi-illuminant portraits based on target skin color.
