Convergence of these stationary linear iterative methods is however notably slow. In this paper we propose the use of Krylov solvers for tomographic linear inversion problems. These advanced iterative methods feature fast convergence at the expense of a higher computational cost per iteration, causing them to be generally uncompetitive without the inclusion of a suitable preconditioner. Combining elements from standard multigrid (MG) solvers and the theory of wavelets, a novel wavelet-based multi-level (WMG) preconditioner is introduced, which is shown to significantly speed-up Krylov convergence. The performance of the WMG-preconditioned Krylov method is analyzed through a spectral analysis, and the approach is compared to existing methods like the classical Simultaneous Iterative Reconstruction Technique (SIRT) and unpreconditioned Krylov methods on a 2D tomographic benchmark problem. Numerical experiments are promising, showing the method to be competitive with the classical Algebraic Reconstruction Techniques in terms of convergence speed and overall performance (CPU time) as well as precision of the reconstruction. }, doi = {doi:10.1016/j.cam.2014.12.044}, author = {Siegfried Cools and Pieter Ghysels and Wim Van Aarle and Jan Sijbers and Wim Vanroose} } @article {1437, title = {Super-resolution for computed tomography based on discrete tomography}, journal = {IEEE Transactions on Image Processing}, volume = {23}, year = {2014}, pages = {1181 - 1193}, doi = {10.1109/TIP.2013.2297025}, author = {Wim Van Aarle and Kees Joost Batenburg and Gert Van Gompel and Elke Van de Casteele and Jan Sijbers} } @article {1407, title = {DART: a new approach for super-resolution reconstruction of license plates}, journal = {Journal of Electronic Imaging}, volume = {22}, year = {2013}, chapter = {041111}, doi = {10.1117/1.JEI.22.4.041111}, url = {http://electronicimaging.spiedigitallibrary.org/article.aspx?articleid=1733763}, author = {Karim Zarei Zefreh and Wim Van Aarle and Kees Joost Batenburg and Jan Sijbers} } @inproceedings {1442, title = {Memory access optimization for iterative tomography on many-core architectures}, booktitle = {The 12th International Meeting on Fully Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine}, year = {2013}, pages = {364-367}, author = {Wim Van Aarle and Pieter Ghysels and Jan Sijbers and Wim Vanroose} } @article {1419, title = {Super-Resolution of License Plate Images using Algebraic Reconstruction Technique}, journal = {Journal of Image and Graphics}, volume = {1}, year = {2013}, month = {2013}, pages = {94 - 98}, publisher = {Engineering and Technology Publishing (ETP)}, address = {USA}, abstract = {In this paper, an iterative super-resolution reconstruction method is introduced for license plate recognition.
