Xin Jin 金鑫

I am an Assistant Professor at the College of Info Science & Technology, Eastern Institute of Technology (EIT) where I cooperated with professor Wenjun Zeng (IEEE Fellow). Our group is to engage in state of the art research in computer vision and deep learning.

Previously, I was a Visiting Scholar of Learning and Vision (LV) Lab at the National University of Singapore where I was guided by professor Xinchao Wang, professor Jiashi Feng and professor Shuicheng Yan. I received Ph.D. degree from University of Science and Technology of China (USTC) in 2022, under the supervision of Zhibo Chen. From Jan. 2019 to July 2020, I work at Intelligent Multimedia Group (IMG) in MSRA under the supervision of Cuiling Lan. From Sep. 2018 to Jan. 2019, I work at KDDI Research, Inc. in Japan under the supervision of Jianfeng Xu.

    I'm interested in image/video coding, person re-id, low-level vision and recently working on large model adaptation, prompt learning with CLIP model, etc.

    Image Coding for Machines with Omnipotent Feature Learning

    ECCV, 2022  
    arxiv /

    In this paper, we attempt to learn a kind of omnipotent feature that is both general (for AI tasks) and compact (for compression) for Image Coding for Machines (ICM). Considering self-supervised learning (SSL) improves feature generalization, we integrate it with the compression task to learn such features.

    Jingwen Ye, Yifang Fu, Jie Song, Xingyi Yang, Songhua Liu, Xin Jin, Mingli Song, Xinchao Wang,
    ECCV, 2022  
    arxiv /

    In this paper, we explore a novel learning scheme, termed as Learning wIth Recoverable Forgetting (LIRF), that explicitly handles the task- or sample-specific knowledge removal and recovery.

    Meta Clustering Learning for Large-scale Unsupervised Person Re-identification
    Xin Jin, Tianyu He, Xu Shen, Tongliang Liu, Xinchao Wang , Jianqiang Huang , Zhibo Chen, Xian-Sheng Hua ,
    ACMMM, 2022  
    arxiv /

    In this paper, we make attempt to the large-scale Unsupervised ReID and propose a “small data for big task” paradigm dubbed Meta Clustering Learning (MCL), which our method significantly saves computational cost while achieving a comparable or even better performance compared to prior works.

    Unleashing the Potential of Unsupervised Pre-Training with Intra-Identity Regularization for Person Re-Identification
    Zizheng Yang, Xin Jin, Kecheng Zheng, Feng Zhao,
    CVPR, 2022  
    arxiv / code /

    We design an Unsupervised Pre-training framework for ReID based on the contrastive learning (CL) pipeline, dubbed UP-ReID.

    Cloth-Changing Person Re-identification from A Single Image with Gait Prediction and Regularization
    Xin Jin, Tianyu He, Kecheng Zheng, Zhiheng Ying, Xu Shen, Zhen Huang , Ruoyu Feng , Jianqiang Huang , Xian-Sheng Hua , Zhibo Chen,
    CVPR, 2022  
    arxiv / code /

    We focus on handling well the Cloth-Changing ReID problem under a more challenging setting, i.e., just from a single image, which enables high-efficiency and latency-free pedestrian identify for real-time surveillance applications.

    Reusing the Task-specific Classifier as a Discriminator: Discriminator-free Adversarial Domain Adaptation
    Lin Chen, Huaian Chen, Zhixiang Wei, Xin Jin, Xiao Tan, Yi Jin, Enhong Chen ,
    CVPR, 2022  
    arxiv / code /

    We address the adversarial-based DA problem from a different perspective and design a simple yet effective adversarial paradigm in the form of a discriminator-free adversarial learning network (DALN), wherein the category classifier is reused as a discriminator.

    Dual Prior Learning for Blind and Blended Image Restoration
    Xin Jin, Li Zhang, Chaowei Shan, Xin Li, Zhibo Chen,
    IEEE TIP, 2021  
    paper /

    We propose the Dual Prior Learning (DPL) method for blind image restoration by taking both image and distortion priors into account. DPL goes beyond DIP (deep image prior) by considering an additional step to explicitly learn the blended distortion prior.

    arxiv /

    The key to solving this more challenging real image super-resolution (RealSR) problem lies in learning feature representations that are both informative and content-aware. We propose an Omni-frequency Region-adaptive Network (OR-Net), here we call features of all low, middle and high frequencies omni-frequency features.

    Global Distance-distributions Separation for Unsupervised Person Re-identification

    Xin Li , Xin Jin, Jianxin Lin, Tao Yu, Sen Liu , Yaojun Wu , Wei Zhou, Zhibo Chen ,

    We introduce the concept of Disentangled Feature Learning to achieve the feature-level divide-and-conquer of hybrid distortions for low-level enhancement.

    Style normalization and restitution for generalizable person re-identification
    Xin Jin, Cuiling Lan, Wenjun Zeng, Zhibo Chen, Li Zhang,
    CVPR, 2020  
    paper / code /

    We propose a simple yet effective Style Normalization and Restitution (SNR) module. Specifically, we filter out style variations (eg, illumination, color contrast) by Instance Normalization (IN). However, such a process inevitably removes discriminative information. We propose to distill identity-relevant feature from the removed information and restitute it to the network to ensure high discrimination.

    Zhizheng Zhang, Cuiling Lan, Wenjun Zeng, Xin Jin, Zhibo Chen,

    Xin Jin, Cuiling Lan, Wenjun Zeng, Guoqiang Wei, Zhibo Chen,
    AAAI, 2020

    Tao Yu, Zongyu Guo, Xin Jin, Shilin Wu, Zhibo Chen, Weiping Li, Zhizheng Zhang, Sen Liu,

    AAAI, 2020

    We show that the mean and variance shifts caused by full-spatial FN limit the image inpainting network training and we propose a spatial region-wise normalization named Region Normalization (RN) to overcome the limitation.
