He obtained his Bachelor and Master degrees in Mathematics (supervised by Prof. Ting-Zhu Huang and Prof. Liang-Jian Deng) from the University of Electronic Science and Technology of China (UESTC), Chengdu, China in 2019 and 2022. His research interests include low-level vision (LV) and AI interpretability.
🔥 Headlines
[08/2025] 🎉🎉🎉 We propose HYPIR: A Step Toward the Next Generation of Image Restoration
HYPIR introduces a simple yet powerful paradigm: fine-tuning a pre-trained diffusion model with adversarial (GAN) loss — no diffusion sampling, no extra adapters. This achieves an unprecedented balance of speed, fidelity, and quality. Initializing GAN training from a pre-trained diffusion model anchors the model near the natural image manifold, ensuring stable training, faster convergence, and superior results — all in a single forward pass.
Official Webpage: The high-speed, high-performance image restoration model is now available on 明犀AI and SupPixel AI.
[03/2025] 🎉🎉🎉 One paper is accepted by TPAMI
We propose a model/task-agnostic interpreting method (CEM) for low-level vision models, bringing causality analysis into the field. We hope this work contributes to a deeper understanding and enhancement of low-level vision models!
Key Insight: Correlation does not imply causation — only causal analysis reveals why.
[02/2025] 🎉🎉🎉 We revisit the generalization problem of low-level vision models
This paper demonstrates that the common strategy of blindly expanding the training set is ineffective. Instead, the key to better generalization lies in guiding the network to learn the image content rather than the degradation!
Takeaway: Teach networks to see the content, not just remove degradation.
[02/2025] 🎉🎉🎉 The book 《底层视觉之美》 has been published
Co-authored with my supervisor Prof. Chao Dong. We hope this book provides valuable insights for researchers and enthusiasts in the Low-level Vision field!
Available on: JD.com
[01/2024] 🎉🎉🎉 We release a groundbreaking image restoration method (SUPIR)
That harnesses the generative prior and the power of model scaling up. Our method demonstrates unprecedented performance in real-world image restoration tasks!
