Stereoscopic Dark Flash for Low-light Photography

no code implementations5 Jan 2019 Jian Wang, Tianfan Xue, Jonathan T. Barron, Jiawen Chen

In this work, we present a camera configuration for acquiring "stereoscopic dark flash" images: a simultaneous stereo pair in which one camera is a conventional RGB sensor, but the other camera is sensitive to near-infrared and near-ultraviolet instead of R and B.

Joint Bilateral Learning for Real-time Universal Photorealistic Style Transfer

3 code implementations ECCV 2020 Xide Xia, Meng Zhang, Tianfan Xue, Zheng Sun, Hui Fang, Brian Kulis, Jiawen Chen

Photorealistic style transfer is the task of transferring the artistic style of an image onto a content target, producing a result that is plausibly taken with a camera.

Real-time Localized Photorealistic Video Style Transfer

no code implementations20 Oct 2020 Xide Xia, Tianfan Xue, Wei-Sheng Lai, Zheng Sun, Abby Chang, Brian Kulis, Jiawen Chen

We present a novel algorithm for transferring artistic styles of semantically meaningful local regions of an image onto local regions of a target video while preserving its photorealism.

How to Train Neural Networks for Flare Removal

1 code implementation ICCV 2021 Yicheng Wu, Qiurui He, Tianfan Xue, Rahul Garg, Jiawen Chen, Ashok Veeraraghavan, Jonathan T. Barron

When a camera is pointed at a strong light source, the resulting photograph may contain lens flare artifacts.

Defocus Map Estimation and Deblurring from a Single Dual-Pixel Image

no code implementations ICCV 2021 Shumian Xin, Neal Wadhwa, Tianfan Xue, Jonathan T. Barron, Pratul P. Srinivasan, Jiawen Chen, Ioannis Gkioulekas, Rahul Garg

We use data captured with a consumer smartphone camera to demonstrate that, after a one-time calibration step, our approach improves upon prior works for both defocus map estimation and blur removal, despite being entirely unsupervised.

The Implicit Values of A Good Hand Shake: Handheld Multi-Frame Neural Depth Refinement

1 code implementation CVPR 2022 Ilya Chugunov, Yuxuan Zhang, Zhihao Xia, Xuaner, Zhang, Jiawen Chen, Felix Heide

Modern smartphones can continuously stream multi-megapixel RGB images at 60Hz, synchronized with high-quality 3D pose information and low-resolution LiDAR-driven depth estimates.

Splatting-based Synthesis for Video Frame Interpolation

no code implementations25 Jan 2022 Simon Niklaus, Ping Hu, Jiawen Chen

Frame interpolation is an essential video processing technique that adjusts the temporal resolution of an image sequence.

Self-Supervised Burst Super-Resolution

no code implementations ICCV 2023 Goutam Bhat, Michaël Gharbi, Jiawen Chen, Luc van Gool, Zhihao Xia

Extensive experiments on real and synthetic data show that, despite only using noisy bursts during training, models trained with our self-supervised strategy match, and sometimes surpass, the quality of fully-supervised baselines trained with synthetic data or weakly-paired ground-truth.

MatSpectNet: Material Segmentation Network with Domain-Aware and Physically-Constrained Hyperspectral Reconstruction

1 code implementation21 Jul 2023 Yuwen Heng, Yihong Wu, Jiawen Chen, Srinandan Dasmahapatra, Hansung Kim

The network leverages the principles of colour perception in modern cameras to constrain the reconstructed hyperspectral images and employs the domain adaptation method to generalise the hyperspectral reconstruction capability from a spectral recovery dataset to material segmentation datasets.

Learning Lens Blur Fields

no code implementations17 Oct 2023 Esther Y. H. Lin, Zhecheng Wang, Rebecca Lin, Daniel Miau, Florian Kainz, Jiawen Chen, Xuaner Cecilia Zhang, David B. Lindell, Kiriakos N. Kutulakos

Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements.

Benchmarking Generation and Evaluation Capabilities of Large Language Models for Instruction Controllable Summarization

1 code implementation15 Nov 2023 Yixin Liu, Alexander R. Fabbri, Jiawen Chen, Yilun Zhao, Simeng Han, Shafiq Joty, PengFei Liu, Dragomir Radev, Chien-Sheng Wu, Arman Cohan

Our study reveals that instruction controllable text summarization remains a challenging task for LLMs, since (1) all LLMs evaluated still make factual and other types of errors in their summaries; (2) all LLM-based evaluation methods cannot achieve a strong alignment with human annotators when judging the quality of candidate summaries; (3) different LLMs show large performance gaps in summary generation and evaluation.
