摘要：

Both segmentation and registration are important image processing tasks in a number of real life applications. While there exist powerful and effective models, many scientific challenges remain open. In this talk, I shall first present some image segmentation work of models and algorithms in two and three dimensions. Then I show some recent works of selective segmentation where pre-defined geometric constraints guide the segmentation models. Finally I introduce some new work on multimodality image registration modeling. Numerical experiments will demonstrate the advantages of our new models and algorithms over existing results. Collaborators related to this work include Noor Badshah (Peshawar, Pakistan), Jian-ping Zhang and Bo Yu (Dalian, China), Lavdie Rada (Liverpool), C Brito (Mexico) and N Chumchob (Thailand).

Ke Chen 教授简介

Ke Chen obtained his BSc degree in Applied Mathematics from Dalian University of Technology in 1983. After taking up a lectureship in the same University for 2 years, he went on to do a MSc degree in Numerical Analysis and Computing in the University of Manchester during 1985-86. During 1987-1990, he completed his Ph.D degree in Numerical Analysis from The University of Plymouth. In 1990, he took up a post-doctoral position in the University of Reading. Then he has been with the University of Liverpool as a lecturer (1993) and a senior lecturer (2001) followed by a reader (2004) and a personal chair professor (2006) in applied mathematics. Since 2008, he has been the director of CMIT. During 2005-2006, he was awarded a Leverhulme research fellowship. He has published more than 100 academic articles, including 69 SCI articles. In 1995, he acquired the status of a chartered mathematician as a fellow of the Institute of Mathematics and its Applications. Since 2004, he has been as editorial advisory board member of five international mathematical journals such as Journal of Applied Mathematics. He was awarded one of the 21 interdisciplinary champions of Liverpool University.
