Yifeng Xu (徐逸峰)

I am a final-year Master student in the VIPL research group at ICT, CAS, supervised by Prof. Shiguang Shan and Prof. Zhenliang He. Before that, I received my B.Eng. from HITsz in 2023, supervised by Prof. Wenjie Pei.

I'm currently interested in generative models and their applications in computer vision / multimodal learning.

Jodi: Unification of Visual Generation and Understanding via Joint Modeling

Yifeng Xu, Zhenliang He, Meina Kan, Shiguang Shan, Xilin Chen

arXiv, 2025

arXiv / code / project page / bibtex

Jodi is a diffusion model that unifies visual generation and understanding by jointly modeling the image domain and multiple label domains, supporting joint generation, controllable generation and image perception.

CtrLoRA: An Extensible and Efficient Framework for Controllable Image Generation

Yifeng Xu, Zhenliang He, Shiguang Shan, Xilin Chen

International Conference on Learning Representations (ICLR), 2025

arXiv / code / bibtex

We propose CtrLoRA, a framework that enables users to efficiently develop controllable generation models for new conditions with minimal data (~1,000 samples) and resources (< 1 hour training on a single GPU).

Hierarchical Contrastive Learning for Pattern-Generalizable Image Corruption Detection

Xin Feng*, Yifeng Xu*, Guangming Lu, Wenjie Pei

International Conference on Computer Vision (ICCV), 2023

pdf / supp / arXiv / code / bibtex

We propose a framework that automatically detects pixel-level corruption masks through hierarchical contrastive learning, enabling effective blind image restoration across diverse corruption patterns.
