SFB goes to Banff, Canada

Otmar Scherzer was a member of the organizing committee of the “Reconstruction Methods for Inverse Problems” workshop in Banff, Canada, June 23-28, 2019. This workshop brought together researchers working on inverse problems coming from medical imaging, non destructive testing, computer vision and geophysics. The PI of sub-project “Quantitative Coupled Physics Imaging”, Peter Elbau and the post-doctoral researcher of the sub-project “Tomography with Uncertainties”, Ekaterina Sherina presented their recent work related to our SFB project.

Reconstruction Methods for Inverse Problems (19w5092)

at Banff, Alberta from Sunday, June 23 to Friday June 28, 2019

Organizers

  • Elena Beretta (NYU Abu Dhabi & Politecnico di Milano)
  • Uri Ascher (University of British Columbia)
  • Otmar Scherzer (University of Vienna)
  • Luminita Vese (University of California, Los Angeles)

Description

Inverse problems require to determine the cause from a set of indirect observations. Such problems appear in medical imaging, non destructive testing of materials, computerized tomography, source reconstructions in acoustics, computer vision and geophysics, to mention but a few. The 21st century is the golden age of computer imaging: Measurement devices have become enormously powerful and huge amounts of data are recorded at every eye glimpse. Moreover, computer technology has developed to such a high degree of efficiency that the evaluation of such an enormous amount of data has become possible *if* adequate mathematical and computational tools are used.

Recently, the community has been exposed to fundamentally new mathematical models (such as learning), which stimulated exciting theoretical developments and new computational algorithms for solving complicated large scale inverse problems. This workshop will survey modern and identify new mathematical and computational developments for tackling such problems.

The first SFB meeting was a success!

In the Obergurgl University Center, the initial SFB “Tomography across the scales” meeting took place, on March, 18-20.  It was attended by the Principal investigators, members, external associated researchers and candidates. The participants had the opportunity, for the first time, to meet all members and interact with people from different disciplines. The talks were interesting covering all “scales”, from mathematics and physics to medical- and bio-sciences.

Everyone is looking forward to the next meeting at the end of the year!

 

Workshop “Inverse Problems in the Alps II”

Then, on March, 21-23, followed the more mathematical oriented workshop “Inverse Problems in the Alps II” co-organized by the SFB, the RICAM and the Doctoral Program “Computational Mathematics”. More than 30 participants enjoyed the talks in this wonderful location. This workshop celebrated also the 60th birthday (\(\varepsilon\) far) of Elena Beretta,  Politecnico di Milano, Italy!
