Joint Face Completion and Super-resolution using Multi-scale Feature Relation Learning

no code implementations29 Feb 2020 Zhilei Liu, Yunpeng Wu, Le Li, Cuicui Zhang, Baoyuan Wu

This paper proposes a multi-scale feature graph generative adversarial network (MFG-GAN) to implement the face restoration of images in which both degradation modes coexist, and also to repair images with a single type of degradation.

Controllable Descendant Face Synthesis

no code implementations26 Feb 2020 Yong Zhang, Le Li, Zhilei Liu, Baoyuan Wu, Yanbo Fan, Zhifeng Li

Most of the existing methods train models for one-versus-one kin relation, which only consider one parent face and one child face by directly using an auto-encoder without any explicit control over the resemblance of the synthesized face to the parent face.
