I am an incoming Ph.D. student at Fei Xia Research Lab @ UC, Irvine, with research interests in Computational Imaging & Photography, particularly in imaging through scattering media and low-level vision. I have earned both my Bachelor’s and Master’s degrees from Huazhong University of Science and Technology (HUST) and Xi’an Jiaotong University (XJTU), respectively. I have previously interned and worked full-time at OPPO and VIVO, where I was responsible for developing ISP algorithms and AI denoising models for smartphones.

Non-invasive multispectral scattering imaging via OTF retrieval.

- Here, we demonstrate a non-invasive multispectral scattering imaging method via optical transfer function (OTF) retrieval. The method uses multi-frame speckles to non-invasively retrieve the OTF of imaging system.
- Our method overcomes the need for invasive measurements and is applicable to a wide range of scenarios for static and dynamic objects, providing a new approach to multispectral imaging.
Non-invasive color imaging through scattering medium under broadband illumination)
Yunong Sun, Jianbin Liu, Hui Chen, Zhuoran Xi, Yu Zhou, Yuchen He, Huaibin Zheng, Zhuo Xu, Yuan Yuan
- Here, we propose a method for retrieving the optical transfer function with several speckle frames within memory effect range to image under broadband illumination. The method can be applied to image amplitude and colored objects under white LED illumination.
- The method based on the mulit-frame speckles provide more reliable results with faster convergence speed than single-shot imaging.
