Xinqi Lin (林心淇)

I am a second-year graduate student at XPixelGroup, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences. I am supervised by Prof. Chao Dong. I also work closely with Dr. Jinjin Gu.

Prior to that, I received my B.Eng. from the Tianjin University (TJU) in 2023.

My current research interest mainly lies in image restoration, image super-resolution.

Research

*: Equal Contribution, †: Corresponding Author

DiffBIR: Toward Blind Image Restoration with Generative Diffusion Prior
Xinqi Lin*, Jingwen He*, Ziyan Chen, Zhaoyang Lyu, Bo Dai, Fanghua Yu, Wanli Ouyang, Yu Qiao, Chao Dong†
European Conference on Computer Vision (ECCV), 2024
paper / project page / code

We present DiffBIR, a general restoration pipeline that could handle different blind image restoration tasks in a unified framework.

Harnessing Diffusion-Yielded Score Priors for Image Restoration
Xinqi Lin, Fanghua Yu, Jinfan Hu, Zhiyuan You, Wu Shi, Jimmy S. Ren, Jinjin Gu†, Chao Dong†
arXiv, 2025
paper / project page / code

We propose a simple and effective method, HYPIR, to achieve a good balance between restoration quality, fidelity, and speed.

Towards Real-world Video Face Restoration: A New Benchmark
Ziyan Chen*, Jingwen He*, Xinqi Lin, Yu Qiao, Chao Dong†
Computer Vision and Pattern Recognition Workshops (CVPRW), 2024
paper / project page / code

We introduced new real-world datasets named FOS with a taxonomy of "Full, Occluded, and Side" faces from mainly video frames to study the applicability of current methods on videos.

VEnhancer: Generative Space-Time Enhancement for Video Generation
Jingwen He, Tianfan Xue, Dongyang Liu, Xinqi Lin, Peng Gao, Dahua Lin, Yu Qiao, Wanli Ouyang†, Ziwei Liu
arXiv, 2024
paper / project page / code

We present VEnhancer, a generative space-time enhancement framework that improves the existing text-to-video results by adding more details in spatial domain and synthetic detailed motion in temporal domain.

AdaptBIR: Adaptive Blind Image Restoration with latent diffusion prior for higher fidelity
Yingqi Liu, Jingwen He, Yihao Liu, Xinqi Lin, Fanghua Yu, Jinfan Hu, Yu Qiao, Chao Dong†
Pattern Recognition(PR), 2024
paper

AdaptBIR aims to help diffusion models get their footing in the low-level vision field, solving the pain point of insufficient fidelity.
