报告题目1： Research and application of image segmentation algorithm

报 告 人：Jinming Duan  PhD,  University of Nottingham, UK

报告人简介：Jinming Duan received the BSc degree from the Nanjing University of information science and technology, PR China, in 2011, and the MSc degree from the Qingdao University, PR China, in 2014. He is currently a second-year PhD student in computer science in the University of Nottingham, UK. His research interest focuses on computer vision and image processing, including image restoration, multiphase image segmentation, implicit surface reconstruction, medical image analysis. He has already published more than 10 peer-review international journal papers, in conjunction with several papers in important conferences.

报告摘要: Segmentation aims to automatically divide an observed image into useful segments of features with sharp boundaries such as buildings, desks, people or trees or organs or cars or whatever are within a picture. In this report, we are concerned with modelling multiple objects in different intensities (so called multiphase segmentation). A major problem to consider is how to represent each region with a characteristic function. Since different characteristic function leads to different computational complexity. Designing a proper characteristic function is thus crucial. In addition, there exist many studies in segmentation of images in planar 2D images. Not all methods can be generalised to the 3D. This report will assess a class of 2D models and methods, and explore the limit of how much we could generalise them to 3D. Both testing and development work will be done in the course. We are mainly concerned with the more reliable variational models. In such high dimensions, fast algorithms development is also a key component. The use of clinical data is linked to some form of CT, MRT, etc. On-going collaboration with oncology experts will be useful on the application and assessment stages.
