Reconstruction of cylindrical surfaces using digital image correlation
(2018-12-01)
A technique for the reconstruction of cylindrical surfaces using optical images with an extension of least squares matching is presented. This technique is based on stereo-image acquisition of a cylindrical object, and it ...
Microscope cell color images segmentation by fuzzy morphological reconstruction
(SPIE Digital Library, 2017-01-26)
There are many different methods to perform gray level segmentation in microscope cell images however, in some circumstances, texture features and roughness are not as relevant as the color for the segmentation task. In ...
MRI-Guided Motion-Corrected PET Image Reconstruction for Cardiac PET/MRI
(SOC NUCLEAR MEDICINE INC, 2021)
Simultaneous PET/MRI has shown potential for the comprehensive assessment of myocardial health from a single examination. Furthermore, MRI-derived respiratory motion information, when incorporated into the PET image ...
Quantitative Susceptibility Map Reconstruction via a Total Generalized Variation Regularization
(IEEE, 2013)
Quantitative susceptibility mapping (QSM) is a last decade new concept which allows to determine the magnetic susceptibility distribution of tissue in-vivo. Nowadays it has several applications such as venous blood oxygenation ...
Performance Improvement of Tomographic Image Reconstruction Based on DSP Processors
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
This paper presents the use of a multiprocessor architecture for the performance improvement of tomographic image reconstruction. Image reconstruction in computed tomography (CT) is an intensive task for single-processor ...

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 ...
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 ...
