Zhihong Zhang

I am a research engineer specializing in computational photography and computer vision. My goal is to develop comprehensive sensing-processing-tasking frameworks that enhance the performance of both low-level and high-level vision tasks. This involves the co-design of front-end imaging systems and backend vision algorithms.

I earned my Ph.D. in Control Science and Engineering from Tsinghua University in 2024, under the guidance of Prof. Jinli Suo. Prior to that, I obtained my B.Eng. in Electronics and Information Engineering from Xidian University in 2019.

My current interests include coded aperture/exposure imaging, low-light imaging, high-speed imaging, deblurring, denoising, event cameras, and diffusion models.

Lightweight High-Speed Photography Built on Coded Exposure and Implicit Neural Representation of Videos

Zhihong Zhang, Runzhao Yang, Jinli Suo*, Yuxiao Cheng, and Qionghai Dai

International Journal of Computer Vision, 2024

Abstract Bib HTML Code

By leveraging classical coded exposure imaging technique and emerging implicit neural representation for videos, we develop a novel self-recursive neural network to sequentially retrieve the latent video sequence from the blurry image utilizing the embedded motion direction cues.

INFWIDE: Image and Feature Space Wiener Deconvolution Network for Non-blind Image Deblurring in Low-Light Conditions

Zhihong Zhang, Yuxiao Cheng, Jinli Suo*, Liheng Bian, and Qionghai Dai

IEEE Transactions on Image Processing, 2023

Abstract Bib HTML Code

Under low-light environment, handheld photography suffers from severe camera shake under long exposure settings. Sophisticated noise and saturation regions are two dominating challenges in practical low-light deblurring. In this work, we propose a novel non-blind deblurring method dubbed image and feature space Wiener deconvolution network (INFWIDE) to tackle these problems systematically.
