FastSwap: A Lightweight One-Stage Framework for Real-Time Face Swapping
Bibliographic record
Abstract
Recent face swapping frameworks have achieved high-fidelity results. However, the previous works suffer from high computation costs due to the deep structure and the use of off-the-shelf networks. To overcome such problems and achieve real-time face swapping, we propose a lightweight one-stage framework, FastSwap. We design a shallow network trained in a self-supervised manner without any manual annotations. The core of our framework is a novel decoder block, called Triple Adaptive Normalization (TAN) block, which effectively integrates the identity and pose information. Besides, we propose a novel data augmentation and switch-test strategy to extract the attributes from the target image, which further enables controllable attribute editing. Extensive experiments on VoxCeleb2 and wild faces demonstrate that our framework generates high-fidelity face swapping results in 123.22 FPS and better preserves the identity, pose, and attributes than other state-of-the-art methods. Furthermore, we conduct an in-depth study to demonstrate the effectiveness of our proposal.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
