Xi CHEN

I am a third-year (starting from 2022) Ph.D. student at the University of Hong Kong, supervised by Prof. Hengshuang Zhao. Before joining HKU, I worked as a senior algorithm engineer at Alibaba Group. Previously, I got the Master degree at Zhejiang University in 2020. I also got a double master diploma at Ecole Centrale Mediterranee(France). Before that, I received my B.Eng. from Zhejiang University in 2017.

My research interests lie in the field of deep learning and computer vision, I've published multiple research works for image/video perception, open-world multi-modal learning. Now I have interests in AIGC, MLLM, and reinforcement learning.

I've done internship or cooperations with many companies like Adobe, Meta, Megvii, SenseTime, Hikvision, Ufoto, AISegment, LIS(France), etc.

I co-supervise interns with some industrial groups. Contact me over gmail (xichen.csai AT gmail) if you are looking for internships or you would like to cooperate with me.

	UniReal: Universal Image Generation and Editing via Learning Real-world Dynamics Xi Chen, Zhifei Zhang, He Zhang, Yuqian Zhou, Soo Ye Kim, Qing Liu, Yijun Li, Jianming Zhang, Nanxuan Zhao, Yilin Wang, Hui Ding, Zhe Lin, Hengshuang Zhao CVPR, 2025 (Highlight) pdf/ page Foundaitional multi-modal generative model cooperated with Adobe. UniReal is a universal framework for multiple image generation and editing tasks. We leverage a video model to handld image tasks by treating different numbers of input/output images as frames. We also seek universal supervisions from video data, thus generating realistic results that understand the world dynamics.
	Zero-shot Image Editing with Reference Imitation Xi Chen, Yutong Feng, Mengting Chen, Yiyang Wang, Shilong Zhang, Yu Liu, Yujun Shen, Hengshuang Zhao NeurIPS, 2024 pdf/ page/ code/ media (AK)/ media (Gradio) GithHub 1.1k stars. MimicBrush conducts imitative editing by discovering the semantic correspondence between the source and reference image. It supports interesting and practical applications for local region composition and texture transfer.
	LivePhoto: Real Image Animation with Text-guided Motion Control Xi Chen, Zhiheng Liu, Mengting Chen, Yutong Feng, Yu Liu, Yujun Shen, Hengshuang Zhao ECCV, 2024 pdf/ page/ code/ media (AK) We present LivePhoto, a real image animation method with text control. Different from previous works, LivePhoto truely listens to the text instructions and well preserves the object-ID.
	AnyDoor: Zero-shot Object-level Image Customization Xi Chen, Lianghua Huang, Yu Liu, Yujun Shen, Deli Zhao, Hengshuang Zhao CVPR, 2024 pdf/ page/ code/ media[AK]/ [量子位]/ [机器之心] Selected as the most influencial papers of CVPR 2024. GithHub 4.2k stars. This work presents AnyDoor, a diffusion-based image generator with the power to teleport target objects to new scenes at user-specified locations in a harmonious way.
	Open-vocabulary Panoptic Segmentation with Embedding Modulation Xi Chen, Shuang Li, Ser-Nam Lim, Antonio Torralba, Hengshuang Zhao ICCV, 2023 pdf/ page We present a omnipotent and efficient framework for open-vocabulary panoptic segmentation, which shows great performance for both closed- and open-vocabulary settings with limited training data.
	FocalClick: Towards Practical Interactive Image Segmentation Xi Chen, Zhiyan Zhao, Yilei Zhang, Manni Duan, Donglian Qi, Hengshuang Zhao CVPR, 2022 pdf / code FocalClick is a simple and effective solution for interactive segmentation. It largely reduces the computation for various models by focusing on target local regions.
	Conditional Diffusion for Interactive Segmentation Xi Chen, Zhiyan Zhao, Feiwu Yu, Yilei Zhang, Manni Duan ICCV, 2021 pdf / code We view interactive segmentation as a diffusion procedure and design feature- and pixel-level diffuion modules for more consistent predictions.
	State-Aware Tracker for Real-Time Video Object Segmentation Xi Chen, Zuoxin Li, Ye Yuan, Gang Yu, Jianxin Shen, Donglian Qi CVPR, 2020 pdf / code We propose a novel pipeline called State-Aware Tracker (SAT), which can produce accurate segmentation results with real-time speed.
