摘要：The imaging science as a research field is increasingly used in many disciplines (Mathematics,Statistics, Physics, Chemistry, Biology, Medicine, Engineering, Psychology, Computer and Information Science etc) because the imaging technology is developed in a fast pace and widely available (with cost down and resolution up). The advance in imaging brings unprecedent challenges and demands on better image analysis techniques based on optimization, geometry and nonlinear partial differential equations, beyond the traditional filtering based linear techniques (FFT, wavelets,Wiener filters etc). Of course, in addition to modeling and analysis, there is an urgent need for advanced, accurate and fast omputational algorithms.
In this talk I shall first discuss variational models that are frequently used for detecting global
features in an image i.e. all objects and their boundaries. These include the Chan-Vese (2001) model of the Mumford-Shah (1989) type and other related models.
