The Mathematics and Cognition, Joint with the Stochastic Modeling Seminar Series, will
present our next lecture on Tuesday, March 19, at 12:15 PM in GWC 604.
Our speaker will be Dr. John Archibald of the Department of Mathematics,
who will speak on the topic:

"High Resolution Image Reconstruction in the Presence of Noise"

Abstract.

 
Gibbs ringing is a well known artifact that effects reconstruction of images having discontinuities. This is a problem in the reconstruction of magnetic resonance data due to the many different tissues that are normally present in each scan. The Gibbs Ringing artifact manifests itself at the boundaries of the tissues, making it difficult to determine the structure of the brain tissue. The Gegenbauer reconstruction method eliminates the effects of Gibbs ringing in imaging.
