You might be upset because the image you acquired from a certain site is of extremely low quality, or you might have a small old photo from your past that you wish to expand. You can now determine the quality of the photo you have using a website called Codeformer. You don’t need to hire an expert to restore outdated, blurry images thanks to this new technology.
So what is Codeformer?
This kickstarter company, based in Berkeley, CA and developed by Shangchen Zhou, Kelvin C.K., Chan Chongyi Li, Chen Change Loy from S-Lab, Nanyang Technological University and known as Codeformer, operates under S-Lab and using artificial intelligence technology to predict blurry photos and make them clearer. They call this technology “face images via self-reconstruction learning.”
Codeformer is similar to GFPGAN in that they both use artificial intelligence to improve images and both have the ability to improve facial features in a photo. However, the difference between the two is that Codeformer tends to improve blurry or unclear faces, while GFPGAN improves missing areas or what they call blind spots.
Codeformer is a cutting-edge AI model designed for robust blind face restoration, particularly in cases where the input images are of very low quality. By employing a learned discrete codebook prior in a small proxy space, it greatly reduces the uncertainty and ambiguity of the restoration mapping process. Codeformer casts blind face restoration as a code prediction task, providing rich visual atoms to generate high-quality faces even when the inputs are severely degraded.
To simulate the global composition and context of low-quality faces for code prediction, the CodeFormer model uses a Transformer-based prediction network. No matter how degraded the input is, this makes it possible to find natural faces that nearly resemble the target faces. A customizable trade-off between fidelity and quality is also made possible via a programmable feature transformation module.
Codeformer outperforms the state-of-the-art in terms of performance in both quality and fidelity, displaying robustness to degradation, thanks to the expressive codebook prior and global modeling.
There are several ways to access Codeformer, either through the replicate.com website as mentioned above or by using huggingface.com.
In general, deep learning-based face restoration algorithms use a variety of ways to create cutting-edge networks. The techniques used mostly concentrate on the following elements: various deep learning architectures, various facial priors, various loss functions, various learning procedures, etc. There are still not enough in-depth and thorough studies on face restoration using deep learning technology, despite the fact that deep learning solutions have dominated the research of face restoration in recent years. The results of Codeformer images cannot be guaranteed to be completely accurate because the system tries to predict the image that is closest to the original using algorithms. However, if there are too many defects in the image or there are unique defects on the face of the person in the photo, this system is still unable to predict it accurately.
