What is ReHiFace-S
ReHiFace-S is an open-source project launched by the Silicon Intelligence team that implements a high-fidelity, real-time face replacement AI algorithm, allowing users to perform face swapping in videos or live streams through simple operations. The features of ReHiFace-S include no data training required, high-fidelity face swapping, support for multi-target face replacement, color correction, one-click rapid deployment, a Gradio interactive interface, and support for the ONNX format, making it easy to deploy across different hardware platforms and deep learning frameworks. It greatly lowers the barrier to face swapping technology and is suitable for fields such as entertainment, film and television production, and VR/AR.
Main features of ReHiFace-S
- Real-time processing capability: Achieves real-time face replacement on hardware such as NVIDIA GTX 1080Ti.
- Zero-shot inference: Supports face replacement without specific training.
- High-fidelity face swapping: Maintains image quality after face swapping through advanced algorithms, making the replacement result look natural and rich in detail.
- Supports ONNX: Performs model conversion and deployment between different deep learning frameworks and hardware platforms based on the ONNX (Open Neural Network Exchange) format.
- Real-time camera mode: Supports capturing images from a real-time camera and performing face replacement, suitable for scenarios such as live streaming and video calls.
- Improved face segmentation model: Uses the Xseg model for more accurate facial segmentation, maintaining good segmentation results even when the face is occluded.
Technical principles of ReHiFace-S
- Deep learning: Based on deep learning algorithms, especially convolutional neural networks (CNN), to recognize and understand facial features.
- Face detection: Uses face detection algorithms to locate faces in images or videos.
- Facial landmark localization: Identifies key facial landmark points, including the positions of the eyes, nose, mouth, etc., for subsequent facial alignment.
- Face segmentation: Separates the face from the background based on face segmentation technology so that the face image can be processed separately.
- Generative adversarial network (GAN): Generates realistic face images based on GAN. GAN includes a generator network, responsible for producing images, and a discriminator network, responsible for evaluating the authenticity of images.
- Facial feature alignment and fusion: Aligns the features of the source face with the features of the target face, and fuses the source face image onto the target face to achieve the face swapping effect.
