String-Averaging Incremental Subgradients for Constrained Convex Optimization with Applications to Reconstruction of Tomographic Images
Rafael Massambone de Oliveira, Elias Salomão Helou, Eduardo Fontoura Costa
We present a method for non-smooth convex minimization which is based on subgradient directions and string-averaging techniques. In this approach, the set of available data is spli…
Superiorization of Incremental Optimization Algorithms for Statistical Tomographic Image Reconstruction
Elias S. Helou, Marcelo V. W. Zibetti, Eduardo X. Miqueles
We propose the superiorization of incremental algorithms for tomographic image reconstruction. The resulting methods follow a better path in its way to finding the optimal solution…
Fast Backprojection Techniques for High Resolution Tomography
Nikolay Koshev, Elias S. Helou, Eduardo X. Miqueles
Fast image reconstruction techniques are becoming important with the increasing number of scientific cases in high resolution micro and nano tomography. The processing of the large…
