Discrete Reconstruction Techniques
DIscrete REConstruction Techniques (DIRECT) is a program system for generating test images, for computing their projections, for performing reconstructions, for comparing reconstructed images, and for visualizing the results. Our framework supplies a solid workflow to be performed during testing DT methods. A collection of DT reconstruction methods is planned to be implemented in this system to...
متن کاملImage Reconstruction Techniques
Image reconstruction in CT is a mathematical process that generates tomographic images from X-ray projection data acquired at many different angles around the patient. Image reconstruction has fundamental impacts on image quality and therefore on radiation dose. For a given radiation dose it is desirable to reconstruct images with the lowest possible noise without sacrificing image accuracy and...
متن کاملMedical Volume Reconstruction Techniques
Medical visualization is the use of computers to create 3D images from medical imaging data sets, almost all surgery and cancer treatment in the developed world relies on it.Volume visualization techniques includes iso-surface visualization, mesh visualization and point cloud visualization techniques, these techniques have revolutionized medicine. Much of modern medicine relies on the 3D imagin...
متن کاملDomain reconstruction using photothermal techniques
A numerical method to detect objects buried in a medium by surface thermal measurements is presented. We propose a new approach combining the use of topological derivatives and Laplace transforms. The original optimization problem with time-dependent constraints is replaced by an equivalent problem with stationary constraints by means of Laplace transforms. The first step in the reconstruction ...
متن کاملMissing data techniques: Feature reconstruction
Automatic speech recognition (ASR) performance degrades rapidly when speech is corrupted with increasing levels of noise. Missing data techniques (MDT) constitute a family of methods that tackle noise robust speech recognition based on the so called missing data assumption proposed in [1]. MDTs assume that (i) the noisy speech signal can be divided in speech-dominated (reliable) and noise-domin...
