FlowFace++: Explicit Semantic Flow-supervised End-to-End Face Swapping

no code implementations22 Jun 2023 Yu Zhang, Hao Zeng, Bowen Ma, Wei zhang, Zhimeng Zhang, Yu Ding, Tangjie Lv, Changjie Fan

The discriminator is shape-aware and relies on a semantic flow-guided operation to explicitly calculate the shape discrepancies between the target and source faces, thus optimizing the face swapping network to generate highly realistic results.

FlowFace: Semantic Flow-guided Shape-aware Face Swapping

no code implementations6 Dec 2022 Hao Zeng, Wei zhang, Changjie Fan, Tangjie Lv, Suzhen Wang, Zhimeng Zhang, Bowen Ma, Lincheng Li, Yu Ding, Xin Yu

Unlike most previous methods that focus on transferring the source inner facial features but neglect facial contours, our FlowFace can transfer both of them to a target face, thus leading to more realistic face swapping.
