  • Perceptual Image Segmentation

    Tue, Oct 30, 2007 @ 11:00 AM - 12:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Wanqing Li, Ph.D.
    University of WollongongAbstract:
    This talk explores the natural mechanisms by which human beings describe and organize images as a means to
    develop a computational model for visual tasks. More specifically, the talk focuses on a model for intermediate
    image segmentation. The model combines features derived from psychological considerations with neurophysiological
    processes. Psychological characteristics are based on Gestalt psychology, in particular we employ
    the gestalt properties of similarity in grey-level, continuity, closure and co-circularity, while physiological
    processing is achieved through the use of Hierarchical Cluster Model (HCM). The motivation for such a study
    stems from the fact that these initiatives will result in an image processing system closely resembling the human
    visual system. An implementation of the model with three level HCM and quantified Gestalt properties will be
    described. Experimental results have shown that the proposed model can produce more consistent results to
    manual segmentation than the well known JSEG and NCuts methods.Bio:
    Wanqing Li received his B.Sc. in physics and electronics and M.Sc. in computer science from Zhejiang
    University, China in 1983 and 1987 respectively. He received his PhD in electronic engineering from The
    University of Western Australia in 1998. He was a Lecturer from 1987 to 1990 and Associate Professor from
    1991 to 1992, both with the Department of Computer Science, Zhejiang University. He joined Motorola
    AustralianResearch Centre in 1998 as a Senior Research Engineer and later became 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 received Motorola CTO's Award in 2003 and is a co-founder of
    the Centre for Multimedia Signal Processing and Content Management at University of Wollongong. His
    current research interests include human motion analysis, multimodal biometric cryptosystems and automatic
    annotation and retrieval of multimedia content and image/video watermarking.Hosted by Prof. C.C.-Jay Kuo
