1.2 论文RestoreFormer

This repo includes the source code of the paper: "RestoreFormer: High-Quality Blind Face Restoration from Undegraded Key-Value Pairs" (CVPR 2022) by Zhouxia Wang, Jiawei Zhang, Runjian Chen, Wenping Wang, and Ping Luo.

RestoreFormer tends to explore fully-spatial attentions to model contextual information and surpasses existing works that use local operators. It has several benefits compared to prior arts. First, it incorporates a multi-head coross-attention layer to learn fully-spatial interations between corrupted queries and high-quality key-value pairs. Second, the key-value pairs in RestoreFormer are sampled from a reconstruction-oriented high-quality dictionary, whose elements are rich in high-quality facial features specifically aimed for face reconstruction.

1.6 自训练Training

sh scripts/run.sh

Note.

The first stage is to attain HQ Dictionary by setting conf_name in scripts/run.sh to 'HQ_Dictionary'.
The second stage is blind face restoration. You need to add your trained HQ_Dictionary model to ckpt_path in config/RestoreFormer.yaml and set conf_name in scripts/run.sh to 'RestoreFormer'.
Our model is trained with 4 V100 GPUs.

2.2 论文RestoreFormer++

This repo is a official implementation of "RestoreFormer++: Towards Real-World Blind Face Restoration from Undegraded Key-Value Paris".
https://arxiv.org/pdf/2308.07228.pdf

RestoreFormer++ is an extension of our RestoreFormer. It proposes to restore a degraded face image with both fidelity and realness by using the powerful fully-spacial attention mechanisms to model the abundant contextual information in the face and its interplay with our reconstruction-oriented high-quality priors. Besides, it introduces an extending degrading model (EDM) that contains more realistic degraded scenarios for training data synthesizing, which helps to enhance its robustness and generalization towards real-world scenarios. Our results compared with the state-of-the-art methods and performance with/without EDM are in following:

RestoreFormer++是RestoreFormer的扩展。它提出了利用强大的全空间注意机制来模拟人脸中丰富的上下文信息及其与我们面向重构的高质量先验的相互作用，以保真度和真实度恢复退化的人脸图像。此外，它还引入了一个扩展的退化模型（EDM），该模型包含更真实的退化场景，用于训练数据合成，这有助于增强其鲁棒性和对真实场景的泛化。我们的结果与最先进的方法和性能有/没有EDM的比较如下：
