ComfyUI Extension: ReActor Node for ComfyUI

comfyui-reactor-node Introduction

The comfyui-reactor-node is an extension designed to facilitate quick and easy face swapping on any image within the ComfyUI environment. This extension is based on the ReActor SD-WebUI Face Swap Extension and allows AI artists to replace faces in images seamlessly. It is particularly useful for tasks such as character animation, creating models for clothing, and other creative projects. The extension operates without censorship filters, making it versatile for various applications, but users are responsible for its ethical use.

How comfyui-reactor-node Works

The comfyui-reactor-node works by identifying faces in a source image and replacing them with faces from a target image. It uses advanced face detection and swapping algorithms to ensure high-quality results. The process involves several steps:

1. Face Detection: The extension detects faces in both the source and target images.
2. Face Swapping: The detected faces are swapped using a face model that ensures the new face fits naturally into the target image.
3. Face Restoration: Optional face restoration models can be applied to enhance the quality of the swapped face. This process is managed through a node-based workflow in ComfyUI, allowing users to customize and control each step.
