Summary

Upscaler's Face Pro feature offers an efficient solution for correcting common face-related errors in AI-generated images, improving their usability by upscaling and fixing details such as eyes, teeth, and facial expressions.

Abstract

The 2023 Creator Tools update introduces Upscaler's Face Pro, a tool designed to address the peculiar artifacts and errors often found in AI-generated human faces, particularly those created by systems like DALL-E. This system not only upscales images by up to 400% but also employs an AI model to reconstruct faces accurately. The article details the common issues with AI-generated faces, such as misplaced eyes, irregular facial features, and inaccurate expressions, which can render an otherwise excellent image unusable. Upscaler's Face Pro setting is highlighted for its ability to significantly improve these images, making them more realistic and suitable for various applications, from marketing campaigns to illustrative content. The process is user-friendly, quick, and can be a valuable asset for those needing to enhance AI-generated faces without extensive manual editing.

Opinions

The author acknowledges AI systems' proficiency in generating human faces but also points out their imperfections, emphasizing the need for tools like Upscaler's Face Pro.
Upscaler is praised for its simplicity and the effectiveness of its new Face Pro feature in correcting AI face generation errors.
The article suggests that while the results may not be perfect, the improvements made by Upscaler's Face Pro are substantial enough to make AI-generated faces more usable.
It is noted that Upscaler's face correction process can introduce a softer look to images, which may be acceptable for most users but is something to consider for those requiring high detail preservation.
The author concludes that Upscaler's system is a significant advancement for those creating illustrative content and can serve as a valuable starting point for professional retouchers working on marketing materials.
A special offer for readers to try Upscaler with 10 free credits is provided, indicating a positive endorsement of the tool's value.

Fix DALL-E Face Issues With Upscaler’s Face Pro

Wonky AI faces, fixed!

AI image generation systems like Dall-E can create some wonky faces. Although these systems are useful for generating AI people, human faces are complex. That means you can often identify an AI-generated image of a person based upon strange errors on the face.

A new system from Upscaler allows users to quickly and easily fix these errors, transforming DALL-E face images into something much more usable. The system also upscales the image at the same time, increasing its size by 400% or more.

Here is our test of Upscaler’s new face correction techniques. Want to try Upscaler out for yourself? We got a special deal that gives our readers 10 free credits to try the system out.

Common Errors with AI Faces

There are a lot of photos of people, which means that AI systems like DALL-E have a lot of training data to learn from when it comes to generating faces. Faces are also relatively predictable, which means that these AI systems became decent at generating them pretty quickly.

Decent, however, is not perfect. Although AI systems can generate plausible faces, systems like Dall-E still struggle to get the details perfect.

Common errors on AI faces include:

Strange placement or shape of the eyes
Extraneous features added around the periphery of the face
Strange issues with teeth or lips
Inappropriate or incorrect facial expressions
Poorly drawn eyebrows, wrinkle lines, or eyelids

Even if the image you generate with AI is otherwise excellent, an error on the face can make it unusable. Fixing these errors manually with tools like Photoshop is time-consuming and requires a talented retoucher.

Fixing AI Faces with Upscaler

We have previously reviewed Upscaler, which is a simple tool for using AI to dramatically increase the size of images produced by Dall-E and other systems. (Our parent company works with Upscaler’s parent company on an unrelated partnership.)

Although it’s not as powerful as tools like Topaz, it has a simple and easy-to-use web interface that makes upscaling very easy.

Upscaler’s system now has a new feature, too. In addition to upscaling images, it now includes a setting called ‘Face Pro’ that automatically fixes wonky AI faces.

The system works by removing the face from the image during the upscaling process, and using an AI model specifically for face reconstruction in order to fix the face before sending the final image to the user. The whole process usually takes about 30 seconds to complete.

Testing the Upscaler Face Pro Setting

Using Face Pro is simple. You select it on the Upscaler page under the “AI Model” section, and then upload your image to upscale as normal.

We tested the Face Pro system with images from two platforms.

DALL-E Face Images

To begin, we started with an image created by Dall-E. Here is the prompt and the resulting image.

As you can see, Dall-e got the general intent correct, but the face has several noticeable errors. The eyes and hairline are strange, there are strange flaws around the ears, and there are some artifacts around the lips.

We ran this Dall-e image through Upscaler with the Face Pro setting selected. Here is the result.

The results aren’t perfect, but they are much better than the original. The AI-generated person’s left eye still looks a little strange, but the artifacting around the lips, the hairline issues, the strange reflections on the face, and the ear shape all look much better. It’s a dramatic improvement, and this image would now be much more usable.

This Person Does Not Exist

For another comparison, we tested the system on the output of Thispersondoesnotexist.com, a popular free AI face generator. The system is based on StyleGAN, an early generative adversarial network face generator created by NVIDIA. The system is specifically tuned to create faces, but it still often creates faces with strange AI issues.

Here’s the sample face that we created with thispersondoesnotexist.com.

It’s fairly convincing, but you can see several issues. There are flaws with the teeth, strange angles in the eyebrows, an unrealistic pattern of wrinkles near the eyes, and a strange shape to the earring.

Here is the result after running the image through Upscaler.

The teeth look much better and more realistic, the eyebrows and eye areas have more convincing patterns and wrinkles, and the earring has more of a natural shape. You might still need to retouch the hair just below the earring, but overall this is a much more convincing-looking face.

We did notice that Upscaler’s system tends to result in a softer look in the original image. This is probably due to the process used to correct the face, rather than the upscaling process, which tends to preserve detail. For many users, the softening probably isn’t an issue, but if you need to keep the original crisp lines in a photo, it’s something to keep in mind.

Conclusion

Overall, we were impressed with Upscaler’s ability to fix AI-generated faces. The system did best when taking very strange Dall-e faces and turning them into something usable.

If you were using one of these faces in a marketing campaign, you’d likely still want the involvement of a professional retoucher. For basic illustrative content, however, Upscaler’s system does a great job.

Even if you’re going to make small corrections to the face, it can also get you well on your way to having a usable face with just a few second’s worth of time.

You can try out Upscaler yourself. We worked with StockPhotos.com, which created the tool, to get a special deal for our readers. Your first 10 credits for the system are free.

Try it out on your own face photos and see if Upscaler’s new system can help make them better and more realistic.
