Work Experience
Technical assistant at Fraunhofer IFF
2023-05 - 2024-04, Magdeburg (Germany)
I developed a industrial-level defect detection solution based on an existing neural network, achieving an AUC score of 97.6% with limited amount of data. This solution features a technique for automatically producing point prompt, which improves the performance of image segmentation on low-contrast images of irregular machinery parts.
- Improved segmentation result through automatic point prompt generation
- A reliable solution unaffected by poor image quality
- High performance regardless of irregular shapes of different machine parts
- Zero-shot solution without the involvement of a large dataset
- Enhanced quality control in industrial processes

Publication and Academic Speech with the Topic "Improved Part-aligned Deep Features Learning for Person Re-Identification"
This is a solution to the challenge of person re-identification (Re-ID) problem. The Re-ID problem is about recognizing and matching pedestrians with different appearances across different cameras.
- Development of a solution to Re-ID problem with the help of computer vision and deep learning methods
- Contributed to a scientific paper, which was accepted by the 16th IEEE International Conference on Advanced Video and Signal-based Surveillance (AVSS)
- Delivered a workshop speech on this conference


Real-Time Detection of Pedestrians and Vehicles in Video Streams of Surveillance Cameras
A deep learning based object detection solution for traffic monitoring inside the campus. Image data was manually collected, labelled and used for training a detector based on a pre-trained YOLOv3 model. The newly trained model shows significant improvement in our use case
- Improvement of 20% in precision compared to the base model
- Improvement on small, obscured, and overlapping objects
- Training of a reliable model with limited data using transfer learning technique


Technical Projects -- Data Engineering
Energy Consumption Analysis of a Commercial Building Using a Generalized Additive Model
This project, which serves as the final project of the course "Regression Analysis", is about the analysis and prediction of the energy consumption in an office building using a Generalized Additive Model (GAM). Data used in this project is originated from an open source dataset, namely "EnerNOC GreenButton Data".
- Implementation of a GAM model with high capability of generalization using R language
- The model exhibits a MAPE (mean absolute percentage error) value of 14.89 when predicting the energy consumption of the next two weeks
- Composing and hosting of a HTML report using R language, Quarto and Github Action

Online R Tutorial Website Based on Quarto
This is a website that contains my study note and projects of R language.
- Developed of a website using Quarto
- Automated deployment using Github Action
Technical Projects -- Software Development and Embedded Systems
Web Application for Image Object Detection Based on Spring Framework
A web application for hosting a deep learning based image object detection with the following function: a user can upload an image and download a new image with bounding boxes, with the detection result is stored in a database.
- Implementation of the Spring Boot backend;
- Deployment of an object detection model using TensorFlow for Java;
- Implementation of MySQL database and Spring Database Connector for storing detection result.


"You Smile I Serve" – A Concept of Smart Restaurant Based on Raspberry-Pi and Python
This project is a prototype of an intelligent restaurant that provides a better customer experience when ordering. A customer is encouraged to smile to a camera to trigger a chatbot and can order their food by talking to this chatbot. A GUI was also developed for the restaurant owner to keep track of customer orders. The main components include a Raspberry Pi single board computer, a microphone, a webcam and a Pi-camera.
- The design of the whole software and hardware structure
- Software implementation of smile detection and QR code reading
- Use of Google Cloud Platform API for implementing the voice recognition function
- Development of a user interface for managing customer's order
