Introducing RestoreFormer++
RestoreFormer++ is an advanced project aimed at enhancing high-quality blind face restoration technologies. It builds on the foundation of the original RestoreFormer, which was designed to improve face restoration using key-value pairs. The project offers various resources and updates to facilitate accessibility and usability for researchers and developers interested in face restoration technology.
Key Features and Updates
-
Code Integration and Access: The code for RestoreFormer has been integrated into a more comprehensive version called RestoreFormer++. All resources related to the project can be accessed via the GitHub repository.
-
Online Demo: A user-friendly online demo was released on September 15, 2023. This demo, available on Hugging Face Gradio, allows users to experience the capabilities of RestoreFormer++ interactively.
-
User-Friendly Inference Methods: RestoreFormer++ provides a comprehensive and user-friendly inference method, which can be explored in detail on the project's GitHub page.
-
Datasets: The project includes several test datasets for users to experiment with and evaluate the performance of RestoreFormer++. These datasets, such as CelebA, LFW-Test, CelebChild-Test, and Webphoto-Test, are available for download on platforms like OneDrive and BaiduYun.
-
Multi-Head Attention and High-Quality Key-Value Pairs: RestoreFormer++ leverages a multi-head cross-attention layer to establish robust spatial interactions between corrupted queries and high-quality key-value pairs. Additionally, it uses a specialized high-quality dictionary to ensure face restoration is conducted with precise and detailed facial features.
Technical Insights
-
Environment Requirements: The project requires Python version 3.7 or higher and relies on libraries such as PyTorch, PyTorch Lightning, OmegaConf, and BasicSR. Users must adhere to these specifications to avoid errors and ensure consistent results.
-
Training and Testing: RestoreFormer++ uses the FFHQ dataset for training, resized to 512x512 pixels to optimize the restoration process. The training is divided into stages, including the creation of an HQ Dictionary and subsequent blind face restoration.
-
Evaluation Metrics: The project provides scripts to run various metrics such as IDD, PSNR, SSIM, and LIPIS, helping users assess the model's performance across different dimensions.
