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.

Selected Research
Video-P2P: Video Editing with Cross-attention Control
Shaoteng Liu, Yuechen Zhang, Wenbo Li, Zhe Lin, Jiaya Jia

Preprint, 2023
Project Page/ Code GitHub Repo stars

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.

Ref-NPR: Reference-Based Non-Photorealistic Radiance Fields
Yuechen Zhang, Zexin He, Jinbo Xing, Xufeng Yao, Jiaya Jia

CVPR, 2023
arXiv / Project Page / Code GitHub Repo stars

We present a controllable scene stylization method utilizing radiance fields to stylize a 3D scene, with a single stylized 2D view taken as reference.

CodeTalker: Speech-Driven 3D Facial Animation with Discrete Motion Prior
Jinbo Xing, Menghan Xia, Yuechen Zhang, Xiaodong Cun, Jue Wang, Tien-Tsin Wong

CVPR, 2023
arXiv / Project Page/ Code GitHub Repo stars

A speech input generates an authentic 3D facial animation based on representations with discrete motion prior.

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 GitHub Repo stars

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 GitHub Repo stars

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.
