Wufei Ma

I am a PhD student at Johns Hopkins University, advised by Bloomberg Distinguished Professor Dr. Alan Yuille.

I obtained my B.S. with summa cum laude honor from Rensselaer Polytechnic Institute in 2020 and I had a double major in Computer Science and Mathematics. During my undergraduate years, I had worked with Prof. Bülent Yener on discriminative and generative models for microstructure images and with Prof. Lirong Xia on preference learning from natural language.

I've spent time at Meta Reality Labs, Microsoft Research Asia, AWS CV Science, and Megvii Research as a research intern.

Hiring: We are recruiting research interns at CCVL. If you are interested in the opportunities, please email me for details.

    ImageNet3D: Towards General-Purpose Object-Level 3D Understanding
    Wufei Ma, Guanning Zeng, Qihao Liu, Letian Zhang, Adam Kortylewski, Yaoyao Liu, Alan Yuille
    Preprint, 2024
    Project Page / Data / Code

    We present ImageNet3D, a large dataset for general-purpose object-level 3D understanding.

    Uncertainty-Aware Deep Video Compression with Ensembles
    Wufei Ma, Jiahao Li, Bin Li, Yan Lu
    IEEE Transactions on Multimedia, 2024
    arXiv / IEEE Xplore

    We propose an uncertainty-aware video compression model that effectively captures the predictive uncertainty with deep ensembles and saves bits by more than 20% when compared to DVC Pro.

    Generating Images with 3D Annotations Using Diffusion Models
    Wufei Ma*, Qihao Liu*, Jiahao Wang*, ..., Adam Kortylewski, Yaoyao Liu, Alan Yuille
    (* denotes equal contribution)
    ICLR, 2024 (Spotlight, 5%)
    Project Page / arXiv / Data (3D-DST images) / Data (aligned 3D models) / Data (LLM-generated captions) / Code

    We propose 3D-DST that generates synthetic data with 3D groundtruth by incorporating 3D geomeotry control into diffusion models. With our diverse prompt generation, we effectively improve both in-distribution (ID) and out-of-distribution (OOD) performance for various 2D and 3D vision tasks.

    3D-Aware Visual Question Answering about Parts, Poses and Occlusions
    Xingrui Wang, Wufei Ma, Zhuowan Li, Adam Kortylewski, Alan Yuille
    NeurIPS, 2023
    arXiv / Code / Dataset

    We introduce Super-CLEVR-3D, a compositional reasoning dataset that contains questions about object parts, their 3D poses, and occlusions. We propose PO3D-VQA, a 3D-aware VQA model that combines probabilistic neural symbolic program execution with 3D generative representations of objects.

    Neural Textured Deformable Meshes for Robust Analysis-by-Synthesis
    Angtian Wang*, Wufei Ma*, Alan Yuille, Adam Kortylewski
    (* denotes equal contribution)
    WACV, 2023
    arXiv

    We introduce Neural Textured Deformable Meshes (NTDM), which learns a neural mesh model with deformable geometry and enables optimization on both camera parameters and object geometries.

    Robust Category-Level 3D Pose Estimation from Synthetic Data
    Jiahao Yang, Wufei Ma, Angtian Wang, Xiaoding Yuan, Adam Kortylewski, Alan Yuille
    WACV, 2023
    arXiv

    We introduce SyntheticP3D, a synthetic dataset for object pose estimation, and CC3D that adapts neural mesh models from synthetic to real data.

    Animal3D: A Comprehensive Dataset of 3D Animal Pose and Shape
    Jiacong Xu, Yi Zhang, Jiawei Peng, Wufei Ma, ..., Alan Yuille, Adam Kortylewski
    ICCV, 2023
    Project Page / arXiv / Dataset

    Animal3D consists of 3379 images collected from 40 mammal species, high-quality annotations of 26 keypoints, and importantly the pose and shape parameters of the SMAL model.

    OOD-CV-v2: An extended Benchmark for Robustness to Out-of-Distribution Shifts of Individual Nuisances in Natural Images
    Bingchen Zhao, Jiahao Wang, Wufei Ma, Artur Jesslen, Siwei Yang, Shaozuo Yu, Oliver Zendel, Christian Theobalt, Alan Yuille, Adam Kortylewski

    Super-CLEVR: A Virtual Benchmark to Diagnose Domain Robustness in Visual Reasoning
    Zhuowan Li, Xingrui Wang, Elias Stengel-Eskin, Adam Kortylewski, Wufei Ma, Benjamin Van Durme, Alan Yuille
    CVPR, 2023 (Highlight, 10% of accepted papers)
    arXiv / Code

    We introduce Super-CLEVR, where different factors in VQA domain shifts can be isolated in order that their effects can be studied independently. We propose probabilistic NSVQA (P-NSVQA), which extends NSVQA with uncertainty reasoning.

    Robust Category-Level 6D Pose Estimation with Coarse-to-Fine Rendering of Neural Features
    Wufei Ma, Angtian Wang, Alan Yuille, Adam Kortylewski
    ECCV, 2022
    arXiv / Code

    We introduce a coarse-to-fine optimization strategy that utilizes the rendering process to estimate a sparse set of 6D object proposals, which are subsequently refined with gradient-based optimization.

    ROBIN: A Benchmark for Robustness to Individual Nuisances
    Bingchen Zhao, Shaozuo Yu, Wufei Ma, Mingxin Yu, Shenxiao Mei, Angtian Wang, Ju He, Alan Yuille, Adam Kortylewski

    Guided Pluralistic Building Contour Completion
    Xiaowei Zhang, Wufei Ma, Gunder Varinlioglu, Nick Rauh, Liu He, Daniel Aliaga
    The Visual Computer, 2022
