Three elliptical models – Single ellipse model Conclusions • Simple in training and efficient in computation − Covering high Chroma skin colors in midtone region – Lightness-dependent ellipse model • Lightness-dependent to adjust skin color ellipses − Fitting skin colors in different lightness levels – Ellipsoid skin color model • Representing compromise − Among complexity, computation efficiency, and detection accuracy 28/29
Results of skin color ellipses – Trained with two different databases – Separate training of Caucasian, Asian, and African skin color • Similar skin type of Caucasian with Asian • More Yellowish and chromatic for Asian than Caucasian • Dark African skin color region − Chromatic in Center of African skin color – Results of skin color ellipsoids in CIELAB and CAM02-UCS • More uniform in skin color area and accurate in CAM02-UCS 29/29
