20th ILAS Conference

Image Restoration and Reconstruction
Organizers: Marco Donatelli (University of Insubria); James G. Nagy (Department of Mathematics and Computer Science, Emory University).

Tentative organizers: Marco Donatelli James G. Nagy.

Image processing is an integral tool used for research in engineering and the sciences, as well as for diagnostic purposes in medicine. The development of efficient and robust algorithms to reconstruct, enhance, restore, and analyze image data often requires use of sophisticated techniques from linear algebra. The talks in this session will report on recent advances made in image restoration and reconstruction, which are used in a wide range of applications, including astronomical and medical imaging. Important linear algebraic aspects can include exploiting particular matrix structure, computing eigenvalues and singular values of very large matrices, and development and analysis of iterative methods for optimization schemes that incorporate certain regularization techniques.
