Lei Tong

Greetings! My name is Lei Tong (Chinese: 童磊). I am currently pursuing a Ph.D. under the guidance of Prof. Huiyu Zhou at the Biomedical Image Processing Lab (BIPL), which is part of the School of Computing and Mathematical Sciences at the University of Leicester. Additionally, I am fortunate to have the supervision and collaboration of Yinhai Wang and Adam Corrigan from AstraZeneca. I am funded by the University of Leicester GTA studentship and the AstraZeneca studentship.

I received my M.Phil. in Computer Science from University of Leicester in 2020, my B.Sc. in Computer Science from Ningbo Institute of Technology, Zhejiang University in 2017. I spent my undergraduate final year at the School of Electronics, Electrical Engineering and Computer Science in Queen's University Belfast.

Research

My research is focusing on computer vision and machine learning, especially in biomedical image analysis, domain generalization and ensemble learning.

	CLANet: A Comprehensive Framework for Cross-Batch Cell Line Identification Using Brightfield Images Lei Tong, Adam Corrigan, Navin Rathna Kumar, Kerry Hallbrook, Jonathan Orme, Yinhai Wang, Huiyu Zhou Medical Image Analysis, 2024 code and dataset In this research, we introduce an innovative approach aimed at minimizing bias across varying bio-batch images by identifying and addressing batch effects in three distinct categories. The outcomes of our study are particularly noteworthy, as they demonstrate that our method diverges from traditional batch correction techniques. Notably, our strategy maintains the discriminative information inherent in bio-batches, while simultaneously improving the distinguishability between different cell lines.
	An automated cell line authentication method for AstraZeneca global cell bank using deep neural networks on brightfield images Lei Tong, Adam Corrigan, Navin Rathna Kumar, Kerry Hallbrook, Jonathan Orme, Yinhai Wang, Huiyu Zhou Scientific Reports, 2022 code In this work, we tansform AI techniques to authentication cell lines. The results can prove our AI method has potentials to complement STR profiling.
	Detecting and Tracking of Multiple Mice Using Part Proposal Networks Zheheng Jiang, Zhihua Liu, Long Chen, Lei Tong, Xiangrong Zhang, Xiangyuan Lan, Danny Crookes, Ming-Hsuan Yang, Huiyu Zhou IEEE Trans. on Neural Networks and Learning Systems, 2022 code / arXiv A novel method to continuously track several mice and individual parts without requiring any specific tagging.
	Cost-sensitive Boosting Pruning Trees for depression detection on Twitter Lei Tong, Zhihua Liu, Zheheng Jiang, Feixiang Zhou, Long Chen, Jialin Lyu, Xiangrong Zhang, Qianni Zhang, Abdul Sadka, Yinhai Wang, Ling Li, Huiyu Zhou IEEE Trans. on Affective Computing, 2022 code / arXiv A novel classifier, namely, Cost-sensitive Boosting Pruning Trees (CBPT), which demonstrates a strong classification ability on two publicly accessible Twitter depression detection datasets..
	Towards advancing the earthquake forecasting by machine learning of satellite data Pan Xiong, Lei Tong, Kun Zhang, Xuhui Shen, Roberto Battiston, Dimitar Ouzounov, Roberto Iuppa, Danny Crookes, Cheng Long, Huiyu Zhou Science of The Total Environment, 2021 code An AdaBoost-based ensemble framework is proposed to forecast earthquake. Our results support a Lithosphere-Atmosphere-Ionosphere Coupling during earthquakes.
	CANet: Context Aware Network for Brain Glioma Segmentation Zhihua Liu, Lei Tong, Long Chen, Feixiang Zhou, Zheheng Jiang, Qianni Zhang, Yinhai Wang, Caifeng Shan, Ling Li, Huiyu Zhou IEEE Trans. on Medical Imaging, 2021 code / arXiv A novel approach named Context-Aware Network (CANet) for brain glioma segmentation.
	Structured Context Enhancement Network for Mouse Pose Estimation Feixiang Zhou, Zheheng Jiang, Zhihua Liu, Fang Chen, Long Chen, Lei Tong, Zhile Yang, Haikuan Wang, Minrui Fei, Ling Li, Huiyu Zhou IEEE Trans. on Circuits and Systems for Video Technology, 2021 code / arXiv A novel Hourglass network based model, namely Graphical Model based Structured Context Enhancement Network (GMSCENet), quantifies mouse pose estimation from videos.
	Perceptual underwater image enhancement with deep learning and physical priors Long Chen, Zheheng Jiang, Lei Tong, Zhihua Liu, Aite Zhao, Qianni Zhang, Junyu Dong, Huiyu Zhou IEEE Trans. on Circuits and Systems for Video Technology, 2020 code / arXiv In this paper, we propose two perceptual enhancement models, each of which uses a deep enhancement model with a detection perceptor. The detection perceptor provides coherent information in the form of gradients to the enhancement model, guiding the enhancement model to generate patch level visually pleasing images or detection favourable images.
