Controlled Wavelet Domain Sparsity in X-ray Tomography
Zenith Purisha, Juho Rimpeläinen, Tatiana Bubba +1
Tomographic reconstruction is an ill-posed inverse problem that calls for regularization. One possibility is to require sparsity of the unknown in an orthonormal wavelet basis. Thi…

Shape recovery from sparse tomographic X-ray data
Heikki Haario, Aki Kallonen, Marko Laine +3
A two-dimensional tomographic problem is studied. The target is assumed to be a homogeneous object bounded by a smooth curve. A Non Uniform Rational Basis Splines (NURBS) curve is…
