Deep Video Prior for Video Consistency and Propagation

1 code implementation27 Jan 2022 Chenyang Lei, Yazhou Xing, Hao Ouyang, Qifeng Chen

A progressive propagation strategy with pseudo labels is also proposed to enhance DVP's performance on video propagation.

Shape from Polarization for Complex Scenes in the Wild

1 code implementation CVPR 2022 Chenyang Lei, Chenyang Qi, Jiaxin Xie, Na Fan, Vladlen Koltun, Qifeng Chen

We present a new data-driven approach with physics-based priors to scene-level normal estimation from a single polarization image.

Towards Photorealistic Colorization by Imagination

no code implementations20 Aug 2021 Chenyang Lei, Yue Wu, Qifeng Chen

We present a novel approach to automatic image colorization by imitating the imagination process of human experts.

A Categorized Reflection Removal Dataset with Diverse Real-world Scenes

no code implementations7 Aug 2021 Chenyang Lei, Xuhua Huang, Chenyang Qi, Yankun Zhao, Wenxiu Sun, Qiong Yan, Qifeng Chen

Due to the lack of a large-scale reflection removal dataset with diverse real-world scenes, many existing reflection removal methods are trained on synthetic data plus a small amount of real-world data, which makes it difficult to evaluate the strengths or weaknesses of different reflection removal methods thoroughly.

Neural Camera Simulators

1 code implementation CVPR 2021 Hao Ouyang, Zifan Shi, Chenyang Lei, Ka Lung Law, Qifeng Chen

To facilitate the learning of a simulator model, we collect a dataset of the 10, 000 raw images of 450 scenes with different exposure settings.

Robust Reflection Removal with Reflection-free Flash-only Cues

1 code implementation CVPR 2021 Chenyang Lei, Qifeng Chen

The flash-only image is equivalent to an image taken in a dark environment with only a flash on.

Blind Video Temporal Consistency via Deep Video Prior

2 code implementations NeurIPS 2020 Chenyang Lei, Yazhou Xing, Qifeng Chen

Extensive quantitative and perceptual experiments show that our approach obtains superior performance than state-of-the-art methods on blind video temporal consistency.

Video Depth Estimation by Fusing Flow-to-Depth Proposals

1 code implementation30 Dec 2019 Jiaxin Xie, Chenyang Lei, Zhuwen Li, Li Erran Li, Qifeng Chen

Our flow-to-depth layer is differentiable, and thus we can refine camera poses by maximizing the aggregated confidence in the camera pose refinement module.
