Selected Projects

Handwritten Chinese Character Generation via Conditional Neural Generative Models    [pdf]
Project for course Machine Learning, UBC

  • Exploited generative adversarial networks (GAN), variational auto-encoders (VAE), and their combinations to generate handwritten Chinese characters conditioned on their GBK encodings
  • Used PyTorch library to build the neural network models

Evaluating Visual Perception with Bouncing Motion    [pdf]  [code]
Project for course Computer Animation, UBC

  • Designed a perceptual experiment and developed a novel interactive interface that supports to investigate human perception to bouncing motions
  • Displayed a rigid ball falling and bouncing from a hill to detect a just noticeable range of plausible motions that loosely follow the law of physics
  • Validated the experiment design and the interface in piloting studies, providing insights to the theory of perception and physical simulation

Connectionist Temporal Classification for Group Activity Recognition in Videos    [pdf]  [poster]
Project for course Machine Learning, SFU

  • Combined VGG Net, recurrent neural network, and connectionist temporal classification (CTC) to recognize a sequence of activities performed by a group of people in a video through supervised learning
  • Constructed a new volleyball dataset using the volleyball game videos available on YouTube.

Distributed File System with Transactional Semantics    [code]
Project for course Programming Parallel and Distributed Systems, SFU

  • Implemented a distributed file system with transactional semantics following the properties of Atomicity, Consistency, Isolation, and Durability using Java
  • Handled omission, byzantine and failstop failures on the client and failstop failures on the server
  • Detail specification

A Simple Ray Tracer    [code]
Project for course Introduction to Computer Graphics, SFU

  • Employed C++ with OpenGL API to implement the ray tracing global illumination model
  • Rendered three spheres and a chess board with shadows, light reflections and refractions
  • Extended the ray tracer to render two glass chess pieces and a glass chess board with their light interactions

QuickActivity: A Web-based Activity Post and Participate System    [code]
Project for course Web-Based Information Systems, SFU

  • Developed a web-based self-service activity-posting and activity-attending platform using Django as development framework
  • Supported the functions of activity searching, posting, attending, bookmarking and other useful features such as printing activity details as PDF files and exporting activity-attending information as CSV files

Automatic Course Arrangement Subsystem    [code]
Project for course Software Engineering, ZJU

  • Developed the subsystem using PHP and MySQL for the back-end and HTML5, CSS3 and JavaScript for the front-end
  • Supported the functions of course arrangement and schedule searching by setting different privileges to different types of users

A Turn-Based Strategy Game    [code]
Project for course Object-Oriented Programming, ZJU

  • Built a LAN-connected turn-based strategy game
  • Used C++ in QT development environment under Linux
  • Connected multiple players in a local area network through TCP/IP using the <QtNetwork> library in QT

Flow Chart Conversion Application    [code]
Project for course Practice on Programming, ZJU

  • Programmed a flow chart conversion application using C in Turbo C
  • Implemented the conversion from text to pixels properly
  • Drew flow charts of every function of the input program on different pages
  • Supported other features such as page selecting by keyboard input
