报告主题:Numerical Methods for solving Medical Imaging Problems


报告摘要:

In this talk, the recent development in global, local, and integration-based meshless computational methods via the use of radial basis function (RBF) will be presented.In particular, the local radial basis function computational method (LRBFCM) is an extension to solve large scale problems which has hindered the practical application of the global RBF method for years due to the ill-conditioning of the resultant full coefficient matrix. The LRBFCM has recently been applied to solve cavity flows problems with free surface andnon-local diffusion problems.Because of the meshless and accurate advantages of RBF approximation, the LRBFCM can solve multi-dimensional boundary value problems (BVPs) under irregular domain with various kinds of stiffness. Numerical examples in 2D will be given to verify the efficiency and effectiveness of the proposed methods. The recent application of this method to solve medical imaging problems will be highlighted. Introduction of collaborativeworkson using machine learning for brain imaging and pattern recognition will also be given.

 

报告人简介:

Prof. BennyHon`s major research interests include meshless computation using radial basis functions for solving various types of partial differential equations and numerical methods for solving inverse problems based on fundamental solutions and reproducing kernels. He is particularly keen inpromoting the meshless radial basis functions method for solving real physical problems such as simulations of tides and waves; multiphasic fluid flows; micro-electro-mechanical systems; inverse heat conduction; nonlocal and nonlinear PDEs; and medical imaging problems.

He is now serving as an Associate Editor for the Journal of Inverse Problems in Science and Engineering (IPSE) and member on the editorial board for seven international journals including the Journals of Advances in Computational Mathematics and Engineering Analysis with Boundary Elements with recent emphasis on meshless and mesh reduction methods. He has also co-edited several special issues on meshless computations and inverse problems for the Journals of Computers and Mathematics with Applications and Advances in Computational Mathematics.
