Facebook AI Edit Text on Images! TextStyleBrush Explained

Science & Technology


Introduction

Imagine you are vacationing in a foreign country where you don’t speak the language. You decide to try a local restaurant, but the menu is entirely in a language you don’t understand. In 2020, you might pull out your phone and use Google Translate to decipher the menu. However, by 2021, you wouldn’t need to navigate through an app anymore; instead, you could utilize a new technology developed by Facebook AI, which translates text in images into your own language seamlessly.

This innovative translation tool employs similar technology to deepfakes, allowing it to modify words in an image while maintaining the original style. By merely using a single word as an example, Facebook AI has created a method for photorealistic language translation in augmented reality. This breakthrough has the potential to revolutionize various sectors, including video games and movies. Imagine being able to effortlessly translate text on buildings, posters, and signs in real-time, enhancing immersion and personalizing experiences for players and viewers alike without the need for manual alterations.

The powerful capabilities of this model extend to handwriting as well. Its exceptional ability to generalize from a single-word example enables it to replicate a text’s style accurately. This feature prioritizes not only the typography but also considers the contextual scene in which it appears, whether on an irregular surface or amidst a complicated background.

Traditional text transfer models rely heavily on supervised learning with precise style images and text segmentation, which is both costly and time-consuming. Facebook AI's approach, however, utilizes a self-supervised training process. During this training, only the word content is provided, while the style and segmentation information are processed without labels. This revolutionary dataset comprises roughly 9,000 images of text across diverse surfaces, combined with single-word annotations. The model learns to generalize the task and applies it in a one-shot transfer manner, adjusting itself to fit any text style based on a mere example.

The overall goal is to separate the content of the text from the image itself, then apply the discovered style onto the new text before reintegrating it into the original image context. This disentanglement resembles the process of taking a photograph of a person and modifying only specific attributes to reflect a different style. This method parallels deepfake technology as well.

The training of this model leverages pre-trained networks for typeface classification and text recognition, enabling a self-supervised learning environment. The absence of direct labels fosters a realistic measure calculated on generated images, with the new text compared against the original text's font style. By using these pretrained networks, the model can learn effectively from unlabeled images, finally generating a modified image with the intended translation.

When an image is inputted, the generator first compresses information into an abstract representation and then applies the style. The innovative use of the StyleGAN-based generator affords precise control over the resolution and appearance of the text, enabling it to maintain a photorealistic quality.

Though there are limitations, particularly in complex scenes where color changes or eliminations can create unrealistic results, this is only the initial iteration of such complex tasks with this level of generalization, and the outcomes thus far are already remarkable. The future of this research holds exciting possibilities.
