In this talk we will introduce optimization methods for tomographic reconstruction. In this talk we will cover the following topics:
- Motivation: tomography as an inverse problem
- Introduction to optimisation: Objective function; Constraints; Statistical interpretation; Maximum Likelihood (ML) and Maximum a Posteriori (MAP) models.
- Optimisation and tomography: Inverse problems formulation; Simple solutions: least squares; Filtered Back Projection as a ML formulation; Algebraic methods as a MAP formulation; Regularization functionals; sparsity; Total Variation.
- Applications: Joint denoising and tomography; Sparse reconstruction; Join segmentation and reconstruction; Local tomography.
- Software packages : Python, Matlab, C++, Fortran packages for optimization. Dedicated tomography packages.
