Accelerating Overrelaxed and Monotone Fast Iterative Shrinkage-Thresholding Algorithms With Line Search for Sparse Reconstructions
(Ieee-inst Electrical Electronics Engineers Inc, 2017-07-01)
Recently, specially crafted unidimensional optimization has been successfully used as line search to accelerate the overrelaxed and monotone fast iterative shrinkage-threshold algorithm (OMFISTA) for computed tomography. ...
Three-dimensional reconstruction of fracture surfaces: Area matching algorithms for automatic parallax measurements
(1999-07-01)
This paper describes two solutions for systematic measurement of surface elevation that can be used for both profile and surface reconstructions for quantitative fractography case studies. The first one is developed under ...

Robust dual reconstruction systems and fusion frames
(Springer, 2012-06)
We study the duality of reconstruction systems, which are g-frames in a finite dimensional setting. These systems allow redundant linear encoding-decoding schemes implemented by the so-called dual reconstruction systems. ...
Impact of view reduction in CT on radiation dose for patients
(Elsevier, 2017)
Iterative methods have become a hot topic of research in computed tomography (CT) imaging because of their capacity to resolve the reconstruction problem from a limited number of projections. This allows the reduction of ...
TRIO a Technique for Reconstruction Using Intensity Order: Application to Undersampled MRI
(2011)
Long acquisition times are still a limitation for many applications of magnetic resonance imaging (MRI), specially in 3-D and dynamic imaging. Several undersampling reconstruction techniques have been proposed to overcome ...
Superiorization of incremental optimization algorithms for statistical tomographic image reconstruction
(Iop Publishing Ltd, 2017-04-01)
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 for the maximum likelihood problem in the ...
Baseline-free Damage Imaging Algorithm using Spatial Frequency Domain Virtual Time Reversal
(2021-01-01)
Structural health monitoring techniques are widely used in industry applications to guarantee the integrity of several types of components. This article proposes a baseline-free damage imaging algorithm based on Spatial ...
