I'm a final-year Ph.D student of Computer Science and Engineering at the University of Michigan, working with David Fouhey. My primary research interest lies in large-scale vision language models, especially for 3D scenes and downstream robotics applications.

Before that, I obtained my B.S.E. from both the University of Michigan and Shanghai Jiao Tong University, and I worked with Jia Deng in Vision & Learning Lab.

I'm currently interning at Nvidia Robotics Lab at Seattle, WA. And I'm actively looking for full-time positions in computer vision. Please feel free to get in touch if there are any opportunities!

Understanding 3D Object Interaction from a Single Image.
Shengyi Qian, David Fouhey.
ICCV 2023

We detect potential 3D object interaction from a single image and a set of query points. Building on Segment-Anything, our model can predict whether the object is movable, rigid, and 3D locations, affordance, articulation, etc.

The paper is also presented at CVPR 2023 Workshop on 3D Vision and Robotics.
Sound Localization from Motion: Jointly Learning Sound Direction and Camera Rotation.
Ziyang Chen, Shengyi Qian, Andrew Owens.
ICCV 2023

We jointly learn to localize sound sources from audio and to estimate camera rotations from images. Our method is entirely self-supervised.

SpotTarget: Rethinking the effect of target edges for link prediction in Graph Neural Networks
MLG @ KDD 2023

We address several common pitfalls in training graph neural networks for link prediction.

[paper]

Understanding 3D Object Articulation in Internet Videos.
CVPR 2022

We propose to investigate detecting and characterizing the 3D planar articulation of objects from ordinary videos.

Recognizing Scenes from Novel Viewpoints.
arXiv 2021

We propose ViewSeg, which takes as input a few RGB images of a new scene and recognizes the scene from novel viewpoints by segmenting it into semantic categories.

Planar Surface Reconstruction from Sparse Views.
ICCV 2021 (Oral)

We create a planar reconstruction of a scene from two very distant camera viewpoints.

Associative3D: Volumetric Reconstruction from Sparse Views.
Shengyi Qian*, Linyi Jin*, David Fouhey.
ECCV 2020

We present Associative3D, which addresses 3D volumetric reconstruction from two views of a scene with an unknown camera, by simultaneously reconstructing objects and figuring out their relationship.

Invited presentation at ECCV 2020 Workshop Holistic Scene Structures for 3D Vision.
OASIS: A Large-Scale Dataset for Single-Image 3D in the Wild.
Weifeng Chen, Shengyi Qian, David Fan, Noriyuki Kojima, Max Hamilton, Jia Deng.
CVPR 2020

We present Open Annotations of Single Image Surfaces (OASIS), a dataset for single-image 3D in the wild consisting of dense annotations of detailed 3D geometry for Internet images.

Learning Single-Image Depth from Videos using Quality Assessment Networks.
Weifeng Chen, Shengyi Qian, Jia Deng.
CVPR 2019

We propose a method to automatically generate training data for single-view depth through Structure-from-Motion (SfM) on Internet videos.
