Brief Bio

Dr Wanqing Li received his B.Sc. in physics and electronics and M.Sc. in computer science from Zhejiang University (Xiqi Campus), China in 1983 and 1987 respectively. In 1997, he received a PhD in electronic engineering from The University of Western Australia. He was a Lecturer from 1987 to 1990 and Associate Professor from 1991 to 1992, both with the Department of Computer Science and Technology, Zhejiang University of China. From 1992 to 1993, he was a visiting Research Fellow with the Computer Science Department, Murdoch University, Australia.  From 1997 to 1998, he worked as an Information Technology Officer with the Bureau of Meteorology, Australia. He joined Motorola Australian Research Centre in 1998 as a Senior Research Engineer and later a Principal Research Engineer. Since 2004, he has been a Senior Lecturer with the School of Computer Science and Software Engineering, University of Wollongong.

Dr. Li is a co-founder of the Centre for Multimedia Signal Processing and Content Management at University of Wollongong. He has 17 years combined industrial and academic research experience in multimedia. He has initiated, led and contributed to a number of successful R&D projects funded by government and industry. He received Motorola CTO’s Award in 2003 due to his significant contribution in the area of video analysis. Dr Li has filed four US patents.  He has authored and co-authored over 50 refereed papers in the field of multimedia signal processing. His current research interests are human motion analysis, multimodal biometric cryptosystems, automatic annotation and intelligent retrieval and adaptation of multimedia content and image/video watermarking. Dr. Li regularly serves  as a committee member and session chair in international conferences and a reviewer of IEEE Transactions.

Research Interests

• Human-centred multimedia analysis

• Multimodal biometrics and crypto-biometrics

• Multimedia security and forensics

• Linguistic description, recognition and prediction of human actions

• Free Videopoint Video (FVV)

Current Projects

• MUVIDA project employs multimodal video analysis to develop technology to correlate and fuse audio and visual information. In particular, the spoken dialogue is analyzed and correlated with associated text extracted from the video; the identity and number of speakers in the scenes is established by using speaker recognition and face tracking algorithms.
• HARR (Human Activity Representation and Recognition) project has developed robust algorithms for human detection, tracking and motion direction estimation and, is currently developing "motion units" and grammar based activity representation and recognition algorithms.
• AISS (Autonomous Intelligent Surveillance System) Research Program aims to develop an adaptive and reconfigurable security surveillance system capable of exploiting environmental information and knowledge base. The system provides continuous detection, tracking and recognition of all human activities within the scene to generate person-specific surveillance report. The program consists of several key enabling projects: multi-modal biometrics, human activity representation and recognition, semantic scene description and representation.
• MUMOBIO (Multi-modal Biometric) Program is developing a continuous human recognition system using gait, face, voice and fingerprint modalities. The system is integrated with the HARR project to enable person-specific surveillance. In addition, the project is addressing the security issues of traditional pattern recognition based biometric systems by developing schemes to bind effectively and efficiently multimodal biometrics with cryptographic keys to form crypto-biometrics systems.
• The Multimedia "Search n Retrieve" Research Program aims to develop methods and tools that can be used in a rapid application development (RAD) environment for multimedia browse, search, and retrieve systems. The systems will employ a multi-modal approach involving, voice, image and video features, text and human cognition.
• RIWD (Robust Image Watermarking Decoding) Project aims to develop a robust decoding method for commonly adopted image watermarking schemes such as Spread Spectrum (SS) and Quantization Index Modulation (QIM). The method  models and estimates the possible attacks that the watermarked images have suffered and incorporates prior knowledge in a maximum posterior probability (MAP) decoding framework.
