CodedStereo: Learned Phase Masks for Large Depth-of-field Stereo
Shiyu Tan*, Yicheng Wu*, Shoou-I Yu, Ashok Veeraraghavan (*: co-first author)
CVPR, 2021  (Oral)

A novel end-to-end optimized stereo system with learned phase masks to achieve high-quality texture and depth reconstruction for large depth-of-field in light-limited environments.

How to Train Neural Networks for Flare Removal
Yicheng Wu, Qiurui He, Tianfan Xue, Rahul Garg, Jiawen Chen, Ashok Veeraraghavan, Jonathan T. Barron
arXiv, 2020
project page / arXiv / bibtex

We propose a novel semi-synthetic pipeline for data generation based on the physics model, and train neural networks to remove lens flare from a single image.

We provide a structured light framework for self-localization of freely moving cameras and scene depth map estimation.

WISHED: Wavefront Imaging Sensor with High Resolution and Depth Ranging
Yicheng Wu*, Fengqiang Li*, Florian Willomitzer, Ashok Veeraraghavan, Oliver Cossairt
(*: co-first author)
ICCP, 2020   (Oral)
project page / paper / video / bibtex

A high depth and lateral resolution 3D sensor for macroscopic rough objects by leveraging wavelength diversity and wavefront sensing.

PhaseCam3D — Learning Phase Masks for Passive Single View Depth Estimation
Yicheng Wu, Vivek Boominathan, Huaijin Chen, Aswin Sankaranarayanan, Ashok Veeraraghavan
ICCP, 2019   (Oral, Best Poster Award)
project page / paper / video / code / bibtex

We jointly optimize the camera hardware (i.e., phase mask) and the algorithm (i.e., neural network) for depth estimation from a single image.

WISH: Wavefront Imaging Sensor with High Resolution
Yicheng Wu, Manoj Kumar Sharma, Ashok Veeraraghavan
Nature - Light: Science & Applications, 2019
project page / paper / code / bibtex

WISH provides wavefront reconstruction with a 10 megapixel resolution, several orders of magnitude better than commercial Shack-Hartmann sensors.

SAVI: Synthetic Apertures for Long-Range, Sub-Diffraction Limited Visible Imaging Using Fourier Ptychography
Jason Holloway, Yicheng Wu, Manoj Kumar Sharma, Oliver Cossairt, Ashok Veeraraghavan
Science Advances, 2017
project page / paper / Rice news / bibtex

We propose to use macroscopic Fourier ptychography as a practical means of creating a synthetic aperture for visible imaging, to achieve sub-diffraction limited resolution.

3DSP Improvements of Measuring the Width of Fraunhofer Diffraction Fringes using Fourier Transform
Yicheng Wu, Jialin Ma, Yi Yang, Ping Sun
Optik-International Journal for Light and Electron Optics, 2015
paper / bibtex

We propose an improved method for calculating the fringe width of Fraunhofer diffraction using Fourier transform.

3DSP Controlling the Wave Propagation through the Medium Designed by Linear Coordinate Transformation
Yicheng Wu, Chengdong He, Yuzhuo Wang, Xuan Liu, Jing Zhou
European Journal of Physics, 2014
paper / bibtex

Based on the principle of transformation optics, we propose to control the wave propagating by linear coordinate transformation.
