Liying Lu

I am a PhD student at the Image and Visual Representation Lab at the École Polytechnique Fédérale de Lausanne (EPFL), where I focus on computer vision and computational photography. I am fortunate to be advised by Prof. Sabine Süsstrunk, and I am also working with Dr. Raphaël Achddou.

Prior to my PhD, I completed my Master's degree at the Deep Vision Lab at The Chinese University of Hong Kong (CUHK). Before that, I earned my Bachelor's degree from Huazhong University of Science and Technology (HUST).

Research

I'm interested in computer vision and computational photography.

Dark Noise Diffusion: Noise Synthesis for Low-Light Image Denoising

Dark Noise Diffusion: Noise Synthesis for Low-Light Image Denoising

Liying Lu, Raphaël Achddou, Sabine Süsstrunk
ICCP / TPAMI, 2025

We generate realistic low-light noise images through a specially designed diffusion model. We analyze the characteristics of the generated noise, and show the denoising results trained with our synthetic data.

Blind Face Restoration under Extreme Conditions: Leveraging 3D-2D Prior Fusion for Superior Structural and Texture Recovery

Blind Face Restoration under Extreme Conditions: Leveraging 3D-2D Prior Fusion for Superior Structural and Texture Recovery

Zhengrui Chen, Liying Lu, Ziyang Yuan, Yiming Zhu, Yu Li, Chun Yuan, Weihong Deng
AAAI, 2024

Combines structure-accurate 3D priors and texture-rich 2D priors in pretrained generative networks for blind face restoration under extreme conditions

Audio-Driven 3D Facial Animation from In-the-Wild Videos

Audio-Driven 3D Facial Animation from In-the-Wild Videos

Liying Lu, Tianke Zhang, Yunfei Liu, Xuangeng Chu, Yu Li
Arxiv Preprint, 2023

We leverage in-the-wild 2D talking-head videos to train a 3D facial animation model.

Best-Buddy GANs for Highly Detailed Image Super-Resolution

Best-Buddy GANs for Highly Detailed Image Super-Resolution

Wenbo Li, Kun Zhou, Lu Qi, Liying Lu, Nianjuan Jiang, Jiangbo Lu
AAAI, 2022

By relaxing the immutable one-to-one constraint of the single image super-resolution task, we allow the estimated patches to dynamically seek the best supervision during training.

Video Frame Interpolation with Transformer

Video Frame Interpolation with Transformer

Liying Lu, Ruizheng Wu, Huaijia Lin, Jiangbo Lu, Jiaya Jia
CVPR, 2022

This paper addresses the task of video frame interpolation, leveraging Transformers to model long-range pixel correlations across video frames.

Revisiting Temporal Alignment for Video Restoration

Revisiting Temporal Alignment for Video Restoration

Kun Zhou, Wenbo Li, Liying Lu, Xiaoguang Han, Jiangbo Lu
CVPR, 2022

We present a generic iterative alignment module which employs a gradual refinement scheme for sub-alignments of video restoration.

MASA-SR: Matching Acceleration and Spatial Adaptation for Reference-Based Image Super-Resolution

MASA-SR: Matching Acceleration and Spatial Adaptation for Reference-Based Image Super-Resolution

Liying Lu, Wenbo Li, Xin Tao, Jiangbo Lu, Jiaya Jia
CVPR, 2021

An approach for recovering high-frequency details in low-quality images by utilizing external reference images. We accelerate the correspondence matching process and introduce an improved feature adaptation method.
