    Learning Clothing and Pose Invariant 3D Shape Representation for Long-Term Person Re-Identification

    Feng Liu, Minchul Kim, Ziang Gu, Anil Jain, Xiaoming Liu

    Long-Term Person Re-Identification (LT-ReID) has become increasingly crucial in computer vision and biometrics. In this work, we aim to extend LT-ReID beyond pedestrian recognition to include a wider range of real-world human activities while still accounting for cloth-changing scenarios over large time gaps. This setting poses additional challenges due to ...

    Controllable and Guided Face Synthesis for Unconstrained Face Recognition

    Feng Liu, Minchul Kim, Anil Jain, Xiaoming Liu

    Although significant advances have been made in face recognition (FR), FR in unconstrained environments remains challenging due to the domain gap between the semi-constrained training datasets and unconstrained testing scenarios. To address this problem, we propose a controllable face synthesis model (CFSM) that can mimic the distribution of target datasets ...

    Voxel-based 3D Detection and Reconstruction of Multiple Objects from a Single Image

    Feng Liu, Xiaoming Liu

    Inferring 3D locations and shapes of multiple objects from a single 2D image is a long-standing objective of computer vision. Most of the existing works either predict one of these 3D properties or focus on solving both for a single object. One fundamental challenge lies in how to learn an ...

    Fully Understanding Generic Objects: Modeling, Segmentation, and Reconstruction

    Feng Liu, Luan Tran, Xiaoming Liu

    Inferring 3D structure of a generic object from a 2D image is a long-standing objective of computer vision. Conventional approaches either learn completely from CAD-generated synthetic data, which have difficulty in inference from real images, or generate 2.5D depth image via intrinsic decomposition, which is limited compared to the ...

    Facial Forgery Detection

    Hao Dang*, Feng Liu*, Joel Stehouwer*, Xiaoming Liu, Anil Jain

    The prevalence of facial recognition, biometric unlock, and social media presents a significant opportunity for bad actors to introduce forged or manipulated images to spread false information or damage reputations. This is aided by the continuing improvement in realistic image synthesis and manipulation by generative adversarial network, GAN, based methods ...
