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…
