Arc2Face ComfyUI Node Library Description

Arc2Face ComfyUI Node Library enhances ComfyUI by integrating nodes that utilize the Arc2Face model to extract face embeddings, generate images from these embeddings, and perform image-to-image transformations.

Arc2Face ComfyUI Node Library Introduction

ComfyUI-Arc2Face is an extension for ComfyUI that leverages the Arc2Face model, developed by foivospar, to provide advanced face embedding extraction and image generation capabilities. This extension allows AI artists to extract facial features from images, generate new images based on these features, and perform transformations between images. It is particularly useful for creating realistic and high-quality facial images, making it a powerful tool for artists working with AI-generated media.

How Arc2Face ComfyUI Node Library Works

ComfyUI-Arc2Face works by using a pre-trained model to extract facial embeddings from input images. These embeddings are numerical representations of the facial features, which can then be used to generate new images or transform existing ones. The process involves several steps:

  1. Face Embedding Extraction: The model identifies and extracts facial features from an input image.
  2. Averaging Embeddings: If multiple faces are detected, the embeddings can be averaged using different methods to create a composite representation.
  3. Image Generation: Using the extracted embeddings, the model generates new images that resemble the input faces.
  4. Image-to-Image Transformation: The model can also transform one image into another by modifying the facial features based on the embeddings.

Arc2Face ComfyUI Node Library Features

Face Embedding Extraction

  • Function: Extracts facial features from images and converts them into numerical embeddings.
  • Customization: You can choose different methods for averaging embeddings if multiple faces are detected.
  • Example: Extracting embeddings from a group photo to create a composite face.

Image Generation

  • Function: Generates new images based on the extracted facial embeddings.
  • Customization: Adjust parameters like the number of images to generate and the level of detail.
  • Example: Creating a new portrait based on the facial features of a given person.

Image-to-Image Transformation

  • Function: Transforms one image into another by modifying the facial features.
  • Customization: Control the degree of transformation and the specific features to modify.
  • Example: Changing the expression or age of a person in a photo.

Image Grid Generation

  • Function: Creates a grid of images for easy comparison.
  • Customization: Specify the directory of images to include in the grid.
  • Example: Comparing different generated images side by side.

Arc2Face ComfyUI Node Library Models

ComfyUI-Arc2Face uses several models to perform its functions. Here are the main models and their purposes:

  1. scrfd_10g_bnkps.onnx: Used for face detection.
  2. arcface.onnx: Used for extracting facial embeddings.
  3. arc2face/config.json and arc2face/diffusion_pytorch_model.safetensors: Used for generating images based on embeddings.
  4. encoder/config.json and encoder/pytorch_model.bin: Used for encoding the facial features. These models need to be placed in specific directories within the ComfyUI models folder for the extension to function correctly.
