Biography

Dr Chua Chin Seng graduated with B.Eng (Honours) (1987-1990) from Nanyang Technological University and Ph.D. (1992-1995) in Computer Vision from Monash University, Australia. He has attained several honours, including two gold medals (IES and Institute of Consulting Eng) for his undergraduate studies, as well as two scholarships from the Federal Government of Australia for his postgraduate work. His industrial experiences include working with Hewlett Packard Singapore as a System Engineer (1986-1987, 1990-1992) and with Defence Science Organisation (1995-1997) as a Research Engineer. Two MINDEF projects (classified) on computer vision were completed during his stay with DSO. Dr Chua joined the University as an academic staff in 1997 and since then has been involved in the several projects in tracking and surveillance using Computer Vision.

Research Interest

Research interests include 2D/3D face recognition, visual surveillance, human activity recognition, gait recognition and general tracking applications.

Selected Research Projects

  • External Research Funding

    1. Principal Investigator for DSO funded project, Vehicle Tracking and Surveillance
    This project investigates methodologies for tracking small targets against a cluttered, moving background.
    2. Investigator for I2R funded project, Digital Signal Processing and Analysis of Speech and Image Data
    This project investigates the recognition of singular human activities.
    3. Co-Principal Investigator for I2R funded project, Intelligent Video Surveillance Systems
    This project investigates intelligent methods of detecting and segmenting humans in video sequences, tracking and analyzing the temporal behavior and activity of detected targets.

  • Locally Funded Research Activities

    1. Principal Investigator for AcRF Project, Localisation and Identification of 3D Objects Using Computer Vision
    This project investigates the recognition of free-forming objects which are represented by their 3D shape, rather than their 2D intensity images. Two potential applications were examined: 3D face recognition and recognition of hand postures.
    2. Principal Investigator for RGM funded project, Further studies in Tracking and Surveillance
    This project investigates the tracking of targets from a moving platform.
