Mini-symposium (MS)

MS17: Modeling and Numerical Methods for Image Problems

Organizers: Wei Zhu, University of Alabama at Tuscaloosa

Abstract:  In the past three decades, variational and PDE-based models have achieved remarkable progresses in mathematical imaging and have been intensively employed in practical applications such as medical image analysis, remote sensing, and machine vision. Recently, efficient neural network based models were developed to deal with different imaging tasks including image classification, segmentation, recognition, etc. The main goal of this symposium is to bring together researchers interested in the modeling and numerical methods for imaging problems using PDE-based method or deep learning
based method.
