What SimSwap is

SimSwap is a free, open-source framework for swapping faces in images and videos with one trained model. It supports aligned and arbitrary images, allowing one face or every face in an image to be replaced. Video modes can target the highest-confidence face, all faces, one specified face, or multiple specified faces. The project documents mask-based blending and bounding-box pasting, recommending a mask for visual results. A beta SimSwap 512 model is available when crop size is set to 512. Example commands add a SimSwap logo watermark by default, with an option to remove it. The documented setup uses Python 3.6+, PyTorch, torchvision, OpenCV, Pillow, NumPy, imageio, moviepy, InsightFace, and timm. Recommended systems are Windows and Ubuntu, with a GPU of at least 3 GB; users without one are directed to a Colab implementation. The CC-BY-NC 4.0 licence limits use to academic and non-commercial purposes.

Who it suits
