Skin-Anatomy Based Face Texture Image Synthesis by Skin Feature Distribution Analyzing Method

This paper investigates solutions to improvement of realistic rendering quality of CG (Computer Graphics) character face. In order to manipulate face skin feature distribution, based on bio-anatomic structure, skin surface is classified into 3 layers (Internal, Regular and Local layer) to control skin base color, surface cellular venation level and noise distribution like freckle, respectively. Moreover, for the feature best re-targeting from real human to virtual character, a new face segmentation method is introduced by analyzing and overlaying the appropriate feature to the deserved area. By doing all above, a specific transformation from real human face skin data to virtual character is proposed which is meaningful for the synthesis of CG texture.
