A Simple Self-calibration Method for The Internal Time Synchronization of MEMS LiDAR

no code implementations26 Sep 2021 Yu Zhang, Xiaoguang Di, Shiyu Yan, Bin Zhang, Baoling Qi, Chunhui Wang

This paper proposes a simple self-calibration method for the internal time synchronization of MEMS(Micro-electromechanical systems) LiDAR during research and development.

Self-supervised Low Light Image Enhancement and Denoising

1 code implementation1 Mar 2021 Yu Zhang, Xiaoguang Di, Bin Zhang, Qingyan Li, Shiyu Yan, Chunhui Wang

Both of the networks can be trained with low light images only, which is achieved by a Maximum Entropy based Retinex (ME-Retinex) model and an assumption that noises are independently distributed.

Better Than Reference In Low Light Image Enhancement: Conditional Re-Enhancement Networks

1 code implementation26 Aug 2020 Yu Zhang, Xiaoguang Di, Bin Zhang, Ruihang Ji, Chunhui Wang

The network takes low light images as input and the enhanced V channel as condition, then it can re-enhance the contrast and brightness of the low light image and at the same time reduce noise and color distortion.

Self-supervised Image Enhancement Network: Training with Low Light Images Only

1 code implementation26 Feb 2020 Yu Zhang, Xiaoguang Di, Bin Zhang, Chunhui Wang

We introduce a constraint that the maximum channel of the reflectance conforms to the maximum channel of the low light image and its entropy should be largest in our model to achieve self-supervised learning.
