VideoFlow: Exploiting Temporal Cues for Multi-frame Optical Flow Estimation

1 code implementation ICCV 2023 Xiaoyu Shi, Zhaoyang Huang, Weikang Bian, Dasong Li, Manyuan Zhang, Ka Chun Cheung, Simon See, Hongwei Qin, Jifeng Dai, Hongsheng Li

We first propose a TRi-frame Optical Flow (TROF) module that estimates bi-directional optical flows for the center frame in a three-frame manner.

KBNet: Kernel Basis Network for Image Restoration

1 code implementation6 Mar 2023 Yi Zhang, Dasong Li, Xiaoyu Shi, Dailan He, Kangning Song, Xiaogang Wang, Hongwei Qin, Hongsheng Li

In this paper, we propose a kernel basis attention (KBA) module, which introduces learnable kernel bases to model representative image patterns for spatial information aggregation.

Efficient Burst Raw Denoising with Variance Stabilization and Multi-frequency Denoising Network

no code implementations10 May 2022 Dasong Li, Yi Zhang, Ka Lung Law, Xiaogang Wang, Hongwei Qin, Hongsheng Li

As for each sub-network, we propose an efficient multi-frequency denoising network to remove noise of different frequencies.


IDR: Self-Supervised Image Denoising via Iterative Data Refinement

1 code implementation CVPR 2022 Yi Zhang, Dasong Li, Ka Lung Law, Xiaogang Wang, Hongwei Qin, Hongsheng Li

To evaluate raw image denoising performance in real-world applications, we build a high-quality raw image dataset SenseNoise-500 that contains 500 real-life scenes.

Image Semantic Transformation: Faster, Lighter and Stronger

no code implementations27 Mar 2018 Dasong Li, Jianbo Wang

We propose Image-Semantic-Transformation-Reconstruction-Circle(ISTRC) model, a novel and powerful method using facenet's Euclidean latent space to understand the images.
