Augmented Reality Advances in Mobile Apps: A Close Look at MediaPipe FaceStylizer and GAN Models

As Seen On

2023 has witnessed a sharp rise in interest surrounding augmented reality (AR)-based smartphone applications, particularly those that allow users to create and modify facial features for short videos, VR, and games. This highly engaging and immersive technology is transforming the way we interact with virtual content, and in the forefront of this development, is the Generation Adversarial Network (GAN) models.

The popularity of face generation and editing models based on GAN approaches has surged extraordinarily, owing to their superior quality and lightweight nature, making them ideal for integration into mobile applications. However, this new frontier is not without its challenges. Most GAN models exhibit high computing complexity and require large training datasets, which can impact both performance and general efficiency.

This is where Google’s MediaPipe FaceStylizer offers a significant breakthrough. Developed by a team of researchers, MediaPipe FaceStylizer is a GAN model-based solution designed for “few-shot face stylization” in AR-based smartphone applications, specifically addressing the issues of model complexity and data efficiency that previously plagued this budding technology.

One of the key features of MediaPipe FaceStylizer is its application of GAN inversion. This groundbreaking technology effectively transforms an image into latent coding for the face generator, resulting in high-quality generation at varying granularities. Concurrently, the model employs a mobile-friendly synthesis network that converts features to RGB at each generator level, ensuring optimal performance and good generation quality.

One of the unique attributes of MediaPipe FaceStylizer is the resort to the StyleGAN model for face production and refinement. Here, the MobileNet V2 core is used for associating input photos with the generated faces, ensuring a precise aesthetic match. The setup shows tremendous promise for enhanced user experiences, offering an extensive range of applications, from building intriguing AR-based games to generating realistic virtual characters.

The MediaPipe FaceStylizer task allows users to create or enhance faces in images and videos from scratch, utilizing the BlazeFaceStylizer model with a face generator and face encoder. Users can further fine-tune the generated faces using the FaceStylizer pipeline and the MediaPipe Model Maker, where only the generator is tweaked, negating the need for massive training datasets.

Google has commendably made the entire solution open-source, providing full access to MediaPipe for potential users and developers alike. Notably, the convenience of using the MediaPipe Model Maker for model fine-tuning further adds to its user-friendly appeal making it a viable tool for AR developers, tech enthusiasts, and new-gen app developers.

With these prolific advancements, however, also comes a range of ethical considerations. As GAN models in AR applications continue to proliferate, it becomes increasingly imperative to address concerns about privacy and the potential misuse of this technology.

In conclusion, despite these concerns, the advances in AR technology, particularly the MediaPipe FaceStylizer, opens a new realm of possibilities in the world of smartphone applications. It’s indeed a fascinating era as we witness breakthroughs and continued innovation in this space.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
