Cosmetic-Vis: Sample-based 3D facial editor for cosmetic medical visualization

© 2017 Copyright held by the owner/author(s). Cosmetic medical visualization has become an important application in computer graphics, especially for facial appearance visualization[Chandawarkar et al. 2013]. Recent approaches have reached very realistic results by blend shape[Ma et al. 2012], which is the most practical tool to make the facial appearance and expression animation in application domains on the entertainment industry (VFXs and games). In many role-playing games (RPGs), players enable to edit the character's facial appearance. However, it is unrealistic since arbitrary discontinuities and position relationship violations (a selected nose might be at a higher position that the bottom of the eyes selected from a different character) caused by players' manual operation. Moreover, the validity on changing facial organs has not be considered well yet.
