I am currently working at Tencent (2024.7-), where my focus is on human motion capture and generation under multimodal inputs. Prior to this, I was a Ph.D. student in Computer Science at Zhejiang University from 2019 to 2024, under the supervision of Xiaowei Zhou. My research interests lie at the intersection of computer vision and computer graphics, with a particular emphasis on 3D human pose estimation and generation, 3D reconstruction, and novel view synthesis.

During my past career, my main focus was on the EasyMoCap repository. The goal of this repository is to make human motion capture more accessible and straightforward. It encompasses a collection of code from my work over the past few years and includes essential tools for the field of human motion capture, such as camera calibration, interactive keypoint annotation, visualization, and more.

    This work proposes a real-time algorithm for reconstructing 3D human poses in crowded scenes from multiple calibrated views. The key challenge of this problem is to efficiently match 2D observations across multiple views. Previous methods perform multi-view matching either at the full-body level, which is sensitive to 2D pose estimation error, or at the part level, which ignores 2D constraints between different types of body parts in the same view. Instead, our approach reasons about all plausible skeleton proposals during multi-view matching, where each skeleton may consist of an arbitrary number of parts instead of being a whole body or a single part. To this end, we formulate the multi-view matching problem as mode seeking in the space of skeleton proposals and develop an efficient algorithm named QuickPose to solve the problem, which enables real-time motion capture in crowded scenes. Experiments show that the proposed algorithm achieves the state-of-the-art performance in terms of both speed and accuracy on public datasets.
