Lin Liu

Currently, I am a graduate student in the School of Information of Science and Technology, University of Science and Technology of China(USTC). Previously, I spent 8 months at the Noah's Ark Lab, Huawei Tech as a research intern, working with Prof. Jianzhuang Liu. I work closely with Shanxin Yuan, Xu Jia, Lingxi Xie and Prof. Qi Tian.

  • Abstract: In recent years, with the development of deep learning, image restoration and enhancement, such as image denoising and image super-resolution, have attracted more and more attention. This talk will focus on the challenges faced by image restoration and propose some solutions: 1) For the problem that real data is difficult to obtain, we introduce methods of synthesizing more real data, self-supervised learning, and fine-tuning using pre-trained models. 2) For the existing models have limited in mining useful information, we first introduce the concept of ‘guidance restoration’, then introduce some self-guidance and external-guidance methods. 3) At last, we introduce some video or burst methods for image restoration.

    I'm interested in low-level vision of computer vision and computational photography.

    Conference Papers:


  • SiamTrans: Zero-Shot Multi-Frame Image Restoration with Pre-Trained Siamese Transformers

    (AAAI), 2022
    Lin Liu, Shanxin Yuan, Jianzhuang Liu, Xin Guo, Youliang Yan, Qi Tian

    We propose a novel zero-shot multi-frame image restoration method for removing unwanted obstruction elements (such as rains, snow, and moire patterns) that vary in successive frames.

  • Self-Adaptively Learning to Demoiré from Focused and Defocused Image Pairs

    Thirty-fourth Conference on Neural Information Processing Systems(NeurIPS), 2020
    Lin Liu, Shanxin Yuan, Jianzhuang Liu, Liping Bao, Gregory Slabaugh, Qi Tian

    We propose a self-adaptive learning method for image demoiréing, which uses an additional input (defocused moiré-free image) to help remove moiré patterns from the focused moiré image.

  • Wavelet-Based Dual-Branch Networkfor Image Demoireing

    European Conference on Computer Vision(ECCV), 2020
    Lin Liu, Jianzhuang Liu, Shanxin Yuan, Gregory Slabaugh, Ales Leonardis, Wengang Zhou, Qi Tian

    We propose a novel wavelet-based and dual-branch neural network for image demoireing. Our network removes moire patterns in the wavelet domain to separate the frequencies of moire patterns from the image content.

  • Joint Demosaicing and Denoising with Self Guidance

    Conference on Computer Vision and Pattern Recognition(CVPR), 2020
    Lin Liu, Xu Jia, Jianzhuang Liu, Qi Tian

    We propose a novel self-guidance network (SGNet) with density-map guidance and green-channel guidance for joint demosaicing and denoising (JDD). And it works well in super-resolution too.

  • Learning Frequency Domain Priors for Image Demoireing

    IEEE Transactions on Pattern Analysis and Machine Intelligence ( TPAMI ), 2021
    Bolun Zheng; Shanxin Yuan; Chenggang Yan; Xiang Tian; Jiyong Zhang; Yaoqi Sun; Lin Liu ; Ales Leonardis; Greg Slabaugh

    In this paper, we raise a general degradation model to describe an image contaminated by moire patterns, and propose a novel multi-scale bandpass convolutional neural network (MBCNN) for single image demoireing.
