Paddlegan provides developers with high-performance implementations of classic and SOTA generated counterwork networks, and supports developers to quickly build, train, and deploy Gan for academic, entertainment, and industrial purposes.
Paddlegan can achieve good results in old video restoration, movement migration, super-resolution, makeup migration, lip synchronization, etc. Some people also used paddegan to realize the dynamic restoration of Du Fu’s portrait, and even made Du Fu “sing a song”.
