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.

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.

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.

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.

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.

Wireless Software Synchronization of Multiple Distributed Cameras

no code implementations21 Dec 2018 Sameer Ansari, Neal Wadhwa, Rahul Garg, Jiawen Chen

We present a method for precisely time-synchronizing the capture of image sequences from a collection of smartphone cameras connected over WiFi.
