Virtual Reality-based Telepresence System for Remote Participant (On-going)
Virtual Reality-based Telepresence System for Remote Participant (On-going)
Goal: This project aims to develop a Telepresence System for Online Learning utilizing Virtual Reality. The system will allow remote users to participate in classes as if they were actually in the physical classroom. The system features recording and streaming of omnidirectional video and audio, which are then displayed to users using a Head-mounted Display for an immersive experience.

Cost-effective 360-degree video streaming over networks (On-going)
Goal: 360-degree video is an essential element in VR/AR systems. To provide an excellent immersive experience, 360-degree videos require extremely high resolution with high frame rate (4K/8K + 60/90 fps). As a result, 360 video has a much higher bandwidth compared with conventional 2D video. The goal of this project is to propose cost-effective delivery methods for bulky 360-degree videos for the wide adoption of VR/AR applications.

Modeling and Evaluating QoE of Video Streaming (On-going)
Modeling and Evaluating QoE of Video Streaming (On-going)
Goal: This project aims to study user perception of various video content types, from traditional videos to Virtual Reality videos, and user-generated content. The main task is to identify the factors affecting the user perception of video content. Various modelling approaches are then applied to build models that can accurately predict user perception of a given content.

Deep Transfer Learning for Recommender System
Goal: Recommender System is playing a key role in providing personalized experience to users of many systems such as E-commerce websites, online news/videos. Despite of significant progress over the past few years, recommender system is still facing the long-standing data sparsity problem. This problem arises due to the fact that each item (i.e., books, movies) are only purchased or rated by a few users, meanwhile the number of items are very large (hundred of thousands). This project aims to address the data sparsity problem in recommender system by means of transfer learning, which is able to transfer knowledge learned from one domain to another related domain.
