A RVR-based Method Bias Field Estimation Brain Magnetic Resonance Images Segmentation
2018/4/19
Abstract— This paper presents a relevance vector regression (RVR) based parametric approach to the bias field estimation in brain magnetic resonance (MR) image segmentation. Segmentation is a very imp...
On the lack of dispersion for a class of magnetic Dirac flows
Dirac equation Strichartz estimates dispersive equations magnetic potential
2011/8/25
Abstract: We show that global Strichartz estimates for magnetic Dirac operators generally fails, if the potentials do not decay fast enough at in?nity. In order to prove this, we construct some explic...
Coding for High-Density Recording on a 1-D Granular Magnetic Medium
High-Density Recording 1-D Granular Magnetic Medium
2011/1/19
In terabit-density magnetic recording, several bits of data can be replaced by the values of their neighbors in the storage medium. As a result, errors in the medium are dependent on each other and al...
