In the human brain, water inside nerve fiber tracts mainly moves
along the fiber direction. DT-MRI (diffusion tensor magnetic resonance
imaging)
measures this movement to indicate location and orientation of the fibers.
The first part of this talk will give a brief introduction to DT-MRI and
its applications.
Regularizing the noisy measured data (smoothing) and isolating
anatomical features
from it (segmentation) are two common tasks in processing DT-MRI data.
The second part of the talk presents a recent contribution to this field,
which adds flexibility to an existing framework for segmentation and
smoothing,
widening its range of applicability
