An Iterative Thresholding Algorithm for Linear Inverse Problems with a Sparsity Constraint

- I. Daubechies, M. Defrise, C. D. Mol
- Mathematics
- 10 July 2003

We consider linear inverse problems where the solution is assumed to have a sparse expansion on an arbitrary preassigned orthonormal basis. We prove that replacing the usual quadratic regularizing… Expand

- Mathematics
- 1 June 2006

A data sufficiency condition for 2D or 3D region-of-interest (ROI) reconstruction from a limited family of line integrals has recently been introduced using the relation between the backprojection of… Expand

Tiny a priori knowledge solves the interior problem

- H. Kudo, M. Courdurier, F. Noo, M. Defrise
- Mathematics, Medicine
- IEEE Nuclear Science Symposium Conference Record
- 7 May 2008

Based on the differentiated backprojection (DBP) framework [1-3], this paper shows that the solution to the interior problem in computed tomography is unique if a tiny a priori knowledge on the… Expand

- Mathematics, Medicine
- Inverse problems
- 12 September 2008

The case of incomplete tomographic data for a compactly supported attenuation function is studied. When the attenuation function is a priori known in a subregion, we show that a reduced set of… Expand
