ZHANG Yuechen, Julian
Hi! Here is ZHANG Yuechen, Julian. I am a second-year Ph.D. student at CUHK, advised by Prof. Jiaya Jia. I also join SmartMore as a computer vision developer.
Before that, I received my B.Sc. degree at CUHK.
My research interests are 3D scene modeling and stylization. I also worked on projects on image segmentation.

Video-P2P: Video Editing with Cross-attention Control
Shaoteng Liu, Yuechen Zhang, Wenbo Li,
Zhe Lin, Jiaya Jia
Preprint, 2023
Project Page/
Code
Add 'Lego' attribute to the child, an edited video is generated. Powered by a novel video inversion process and cross-attention control. We also find that a Decoupled-Guidance strategy is essential for video editing.

R2Former: Probing Region Relationship in Semantic Segmentation Transformers
Yuechen Zhang,
Tiancheng Shen*, Huaijia Lin, Lu Qi, Eric Lo, Jiaya Jia
Preprint, 2022
R2Former decomposes the relationships into intra-region ones and inter-region ones. With such modifications, the performance of mask classification can be improved on widely used semantic segmentation benchmarks.

High Quality Segmentation for Ultra High-resolution Images
Tiancheng Shen,
Yuechen Zhang,
Lu Qi, Jason Kuen, Xingyu Xie, Jianlong Wu, Zhe Lin, Jiaya Jia
CVPR, 2022
Paper
/
Code
We propose the Continuous Refinement Model (CRM) for the ultra high-resolution mask refinement. CRM aligns the feature with the refinement target and aggregates them to reconstruct image details.

PCL: Proxy-based Contrastive Learning for Domain Generalization
Xufeng Yao, Yang Bai, Xinyun Zhang,
Yuechen Zhang,
Qi Sun, Ran Chen, Ruiyu Li, Bei Yu
CVPR, 2022
Paper
/
Code
We propose a novel proxy-based contrastive learning method, which replaces the original sample-to-sample relations with proxy-to-sample relations, significantly alleviating the positive alignment issue.
