Prasanna Muralidharan Presents:Bayesian regression and longitudinal modeling of manifold data: Applications to timevarying shape analysisApril 21, 2017 at 11:30am for 1hr


Abstract:The statistical study of anatomical shape is of crucial importance in many medical image analysis applications, specifically in the context of understanding healthy brain developmental processes and those with neurological disorders such as Alzheimer's and Huntington's disease. Shape, defined as the geometry of an object invariant to position, size and orientation, is nonlinear. Therefore traditional Euclidean statistics for shape analysis are not appropriate.

Gunther Uhlmann, Walker Family Endowed Professor of Mathematics, University of Washington Presents:Travel Time TomographyApril 21, 2017 at 2:00pm for 1hr


Abstract:We will consider the inverse problem of determining the sound speed or index of refraction of a medium by measuring the travel times of waves going through the medium. This problem arises in global seismology in an attempt to determine the inner structure of the Earth by measuring travel times of earthquakes. It has also applications in optics and medical imaging among others.
