Xiaoyu Shi 石晓宇

I am a 4th-year Ph.D student at MMLab of the Chinese University of Hong Kong, advised by Prof. Hongsheng Li. Prior to this, I obtained Bachelor of Engineer & Bachelor of Science degrees from Zhejiang University and Simon Fraser University, respectively. I'm interested in computer vision and machine learning, with a special focus on video generation and correspondence learning.

	Motion-I2V: Consistent and Controllable Image-to-Video Generation with Explicit Motion Modeling Xiaoyu Shi, Zhaoyang Huang, Fu-Yun, Wang, Weikang Bian, Dasong Li, Yi Zhang, Manyuan Zhang, Kachun Cheung, Simon See, Hongwei Qin, Jifeng Dai, Hongsheng Li Arxiv, 2024 Paper / Code We introduce Motion-I2V, a novel framework for consistent and controllable image-to-video generation (I2V). In contrast to previous methods that directly learn the complicated image-to-video mapping, Motion-I2V factorizes I2V into two stages with explicit motion modeling.
	Context-TAP: Tracking Any Point Demands Spatial Context Features Weikang Bian, Zhaoyang Huang, Xiaoyu Shi, Yitong Dong, Yijin Li, Hongsheng Li NeurIPS, 2023 Project page / Paper We set new SOTA on the task of Tracking Any Point (TAP) by introducing rich spatial context features.
	A Unified Conditional Framework for Diffusion-based Image Restoration Yi Zhang, Xiaoyu Shi, Dasong Li, Xiaogang Wang, Hongsheng Li NeurIPS, 2023 Project page / Paper / Code A unified conditional framework based on diffusion models for image restoration.
	VideoFlow: Exploiting Temporal Cues for Multi-frame Optical Flow Estimation Xiaoyu Shi, Zhaoyang Huang, Weikang Bian, Dasong Li, Manyuan Zhang, Kachun Cheung, Simon See, Hongwei Qin, Jifeng Dai, Hongsheng Li ICCV, 2023 Paper / Code First method to achieve sub-pixel accuracy on the Sintel benchmark. 19.2% error reduction from the best published result on the KITTI-2015 benchmark.
	BlinkFlow: A Dataset to Push the Limits of Event-based Optical Flow Estimation Yijin Li, Zhaoyang Huang, Shuo Chen, Xiaoyu Shi, Hongsheng Li, Hujun Bao, Zhaopeng Cui, Guofeng Zhang IROS, 2023 Paper We build a benchmark BlinkFlow for training and evaluating event-based optical flow estimation method.

	FlowFormer++: Masked Cost Volume Autoencoding for Pretraining Optical Flow Estimation Xiaoyu Shi, Zhaoyang Huang, Dasong Li, Manyuan Zhang, Kachun Cheung, Simon See, Hongwei Qin, Jifeng Dai, Hongsheng Li CVPR, 2023 Paper / Code Ranks 1st on Sintel Optical Flow benchmark on Mar. 1st, 2023.
	A Simple Baseline for Video Restoration with Spatial-temporal Shift Dasong Li, Xiaoyu Shi, Yi Zhang, Kachun Cheung, Simon See, Xiaogang Wang, Hongwei Qin, Hongsheng Li CVPR, 2023 Project Page / Paper / Code Our approach is based on grouped spatial-temporal shift, which is a lightweight technique that can implicitly capture inter-frame correspondences for multi-frame aggregation.
	FlowFormer: A Transformer Architecture for Optical Flow Zhaoyang Huang, Xiaoyu Shi, Chao Zhang, Qiang Wang, Kachun Cheung, Hongwei Qin, Jifeng Dai, Hongsheng Li ECCV, 2022 Project Page / Paper / Code Ranks 1st on Sintel Optical Flow benchmark on Mar. 17th, 2022.
	Decoupled spatial-temporal transformer for video inpainting Rui Liu, Hanming Deng, Yangyi Huang, Xiaoyu Shi, Lewei Lu, Wenxiu Sun, Xiaogang Wang, Jifeng Dai, Hongsheng Li Arxiv, 2021 Paper / Code We propose a novel decoupled spatial-temporal Transformer (DSTT) framework for video inpainting to improve video inpainting quality with higher running efficiency.
