Clearer Frames, Anytime: Resolving Velocity Ambiguity in Video Frame Interpolation

1 code implementation14 Nov 2023 Zhihang Zhong, Gurunandan Krishnan, Xiao Sun, Yu Qiao, Sizhuo Ma, Jian Wang

Existing video frame interpolation (VFI) methods blindly predict where each object is at a specific timestep t ("time indexing"), which struggles to predict precise object movements.

Rethinking Video Frame Interpolation from Shutter Mode Induced Degradation

no code implementations ICCV 2023 Xiang Ji, Zhixiang Wang, Zhihang Zhong, Yinqiang Zheng

Image restoration from various motion-related degradations, like blurry effects recorded by a global shutter (GS) and jello effects caused by a rolling shutter (RS), has been extensively studied.

NIR-assisted Video Enhancement via Unpaired 24-hour Data

1 code implementation ICCV 2023 Muyao Niu, Zhihang Zhong, Yinqiang Zheng

In this paper, we defend the feasibility and superiority of NIR-assisted low-light video enhancement results by using unpaired 24-hour data for the first time, which significantly eases data collection and improves generalization performance on in-the-wild data.

Blur Interpolation Transformer for Real-World Motion from Blur

1 code implementation CVPR 2023 Zhihang Zhong, Mingdeng Cao, Xiang Ji, Yinqiang Zheng, Imari Sato

This paper studies the challenging problem of recovering motion from blur, also known as joint deblurring and interpolation or blur temporal super-resolution.

Towards Real-World Video Deblurring by Exploring Blur Formation Process

1 code implementation28 Aug 2022 Mingdeng Cao, Zhihang Zhong, Yanbo Fan, Jiahao Wang, Yong Zhang, Jue Wang, Yujiu Yang, Yinqiang Zheng

We believe the novel realistic synthesis pipeline and the corresponding RAW video dataset can help the community to easily construct customized blur datasets to improve real-world video deblurring performance largely, instead of laboriously collecting real data pairs.

Learning Adaptive Warping for Real-World Rolling Shutter Correction

1 code implementation CVPR 2022 Mingdeng Cao, Zhihang Zhong, Jiahao Wang, Yinqiang Zheng, Yujiu Yang

This paper proposes the first real-world rolling shutter (RS) correction dataset, BS-RSC, and a corresponding model to correct the RS frames in a distorted video.

Bringing Rolling Shutter Images Alive with Dual Reversed Distortion

1 code implementation12 Mar 2022 Zhihang Zhong, Mingdeng Cao, Xiao Sun, Zhirong Wu, Zhongyi Zhou, Yinqiang Zheng, Stephen Lin, Imari Sato

In this paper, instead of two consecutive frames, we propose to exploit a pair of images captured by dual RS cameras with reversed RS directions for this highly challenging task.

Real-world Video Deblurring: A Benchmark Dataset and An Efficient Recurrent Neural Network

1 code implementation ECCV 2020 Zhihang Zhong, Ye Gao, Yinqiang Zheng, Bo Zheng, Imari Sato

Real-world video deblurring in real time still remains a challenging task due to the complexity of spatially and temporally varying blur itself and the requirement of low computational cost.

Towards Rolling Shutter Correction and Deblurring in Dynamic Scenes

1 code implementation CVPR 2021 Zhihang Zhong, Yinqiang Zheng, Imari Sato

Since direct application of existing individual rolling shutter correction (RSC) or global shutter deblurring (GSD) methods on RSCD leads to undesirable results due to inherent flaws in the network architecture, we further present the first learning-based model (JCD) for RSCD.
