Enhancing AI-Generated Faces with GFP-GAN Techniques

Written on

Chapter 1: Introduction to AI Face Restoration

The world of AI art is fascinating, but certain aspects, such as peculiar eye shapes, can make generated images unsettling. However, before you discard your creations, there’s a solution to enhance them! This guide will demonstrate how to refine AI-generated portraits, even those that appear nearly flawless. A slight adjustment to the eyes can dramatically shift an image from looking artificial to photorealistic.

Example of AI-generated face enhancement

Section 1.1: Understanding GFP-GAN

GFP-GAN, which stands for Generative Facial Prior Generative Adversarial Network, is a powerful tool designed to restore and enhance facial images. Utilizing advanced machine learning techniques, it learns to interpret and reconstruct facial features from incomplete data. You can explore more about this technology in the linked resources.

BaseTen, utilizing the GFP-GAN model, can enhance your images in two main ways:

  1. Overall image sharpening.
  2. Targeted corrections, particularly for facial features like eyes and teeth.

Furthermore, BaseTen increases image resolution, making it ideal for high-quality prints or detailed applications. To use BaseTen, simply navigate to their website, upload your image, and click "restore photo." The software will then process your image.

It's important to note that results may vary based on the original image's quality, but generally, users can expect noticeable improvements in clarity and detail.

Section 1.2: Practical Usage of BaseTen

Here’s an illustration of how BaseTen can elevate older AI images. For instance, experimental images from 2015 were significantly enhanced using BaseTen in 2022. While not every image yields stellar results, many do show marked improvement.

Currently, BaseTen is available for free; however, the developers, Tencent, are reportedly considering a subscription model for advanced features, which could limit access for some users. Therefore, it’s advisable to download the Python version of GFP-GAN on Google Colab.

Chapter 2: Utilizing Google Colab for GFP-GAN

Google Colab is a free cloud-based Jupyter Notebook environment that allows users to run Python code without the need for installation. To get started with the GFP-GAN on Google Colab:

  1. Visit the GFPGAN Colab page.
  2. Go to FILE and select "Save a copy in Drive."
  3. Close the original tab.
  4. Connect to a Google GPU by clicking CONNECT.
  5. Confirm GPU mode under MENU > Runtime > Change runtime type.

Now you're ready to begin!

Instructions for Using GFP-GAN

The process of utilizing GFP-GAN involves five straightforward steps:

  1. Preparations: Execute the first cell by hitting play.
  2. Upload Images: In the second cell, hit play, wait for the green check, and upload your image.
  3. Inference: Hit play to see the software process your image.
  4. Visualize: Hit play again to view your enhanced images.
  5. Download Results: Finally, hit play to download a zip file containing your results.

The downloaded zip folder will include four subdirectories:

  • cmp: Side-by-side comparisons of before and after images.
  • cropped_faces: Cropped sections of the corrected areas.
  • restored_faces: Enhanced cropped faces.
  • restored_imgs: The fully corrected overall image (this is the one you want).

And that's it! You can repeat the process for additional images or upload multiple files, although processing them one at a time is recommended for optimal results.
