CASIA researchers released a face swapping survey and benchmark on April 27, 2026, aiming to standardize evaluation across fragmented GAN and diffusion model methods. Qi Li, Weining Wang, and colleagues published a comprehensive face swapping survey and the CASIA FaceSwapping benchmark on arXiv on April 27, 2026. The benchmark targets the fragmented evaluation landscape across GAN and diffusion model methods. Key facts Paper submitted to arXiv on April 27, 2026. CASIA FaceSwapping benchmark has balanced demographic distributions. Survey organizes methods into five paradigms. Standardized protocols assess robustness across attribute variations. Code available at github.com/CASIA-NLPRAI/face-swapping-survey. Face swapping research has advanced rapidly with GANs and diffusion models, but evaluation remains a mess. A new arXiv paper from CASIA researchers attempts to clean it up.…
