Description of the Program
This program is intended to foster research, learning and collaboration
between distinguished researchers in the various areas of Image
Analysis. There will be a number of short courses devoted to various
topics in Image Analysis and Compressed Sensing. These courses are
aimed at attracting graduate students and postdoctoral fellows and
at helping define the research questions to be investigated during
the program.
In addition, there will be research talks by the participants in
the program.
Preliminary topics for the program:
- L1 minimization and applications (including Total Variation
minimization).
- Compressed Sensing by variational regularization methods.
- Proximal point methods and iterative methods for solving ill-posed
inverse problems (including iterative Bregman methods, hierarchical
decompositions, surrogate functionals).
- Geometric processing (denoising of surfaces, non-rigid shape
processing and analysis).
- Optimal Transportation and Wasserstein Distance methods for
registration and segmentation.
- PDE methods for image processing.
- Nonlocal methods (nonlocal means, nonlocal total variation,
bilateral filtering).
