More Information

Associate Professor Tan received his B.Eng (First Class Hons) and PhD degree from University of Surrey in the UK in 1990 and 1993 respectively. He has well over 15 years of research and development experience in the fields of computer vision, large scale spatial and temporal data analysis and multi-modal processing. He pioneered the approach of using image synthesis techniques to improve the performance of face recognition systems. This approach makes it possible for face recognition systems to be deployed in outdoor and uncontrolled environment while still maintaining high accuracy performance and low error rate.

Assoc Prof Tan's interest in physical security extends to him exploring the benefits of deploying security risk management processes to plug the gaps of security technologies pitfalls. One of his current research interests concerns using modelling and simulation techniques to perform security risk assessments to protect and secure large scale and complex infrastructures.

Research Interests

My research interest span a broad range of areas ranging from (physical) security, multi-modal analysis and exploring computer vision and computer graphics convergence. I apply these to many interesting real-world problems that are both serious and fun. If you have any interests in these areas, please send me an email.
