Data-Driven Geometric Face Image Smilization Featuring Moving Least Square Based Deformation
With the prosperous development of the Internet, virtual identity is becoming more important to people in social life. As one key factor, attractiveness, is a significant part of virtual identity, where there is still room for different strategies to improve attractiveness. In this study, we focus on digital face image and make it a little bit smiling as a common way to improve attractiveness. The workflow includes face detection, face alignment and image deformation. By only deforming geometrically, our method reaches the smile rate at 53.96% while natural smile image has 89.29% smile rate, based on crowd sourcing experimental results on our test set.
