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. ...
Ellipse-based principal component analysis for self-intersecting curve reconstruction from noisy point sets
(SPRINGER, 2011-03-01)
Surface reconstruction from cross cuts usually requires curve reconstruction from planar noisy point samples. The output curves must form a possibly disconnected 1-manifold for the surface reconstruction to proceed. This ...
Duality in reconstruction systems
(Elsevier Science Inc, 2012-02)
We consider reconstruction systems (RS's), which are G-frames in a finite dimensional setting, and that includes the fusion frames as projective RS's. We describe the spectral picture of the set of RS operators for the ...
Reconstruction of positron emission tomography images using adaptive sliced remeshing strategy
(Society of Photo-Optical Instrumentation Engineers, 2021-03)
Purpose: The reconstruction of positron emission tomography images is a computationally intensive task which benefits from the use of increasingly complex physical models. Aiming to reduce the computational burden by means ...
Climate indices in historical climate reconstructions: a global state-of-the-art
(Copernicus Publications, 2021-06)
Narrative evidence contained within historical documents and inscriptions provides an important record of climate variability for periods prior to the onset of systematic meteorological data collection. A common approach ...
Sampling and reconstruction by means of weighted inverses
(Springer, 2020-06)
In this article, we address the problem of reconstructing an element in a Hilbert space from its samples by means of a weighted least square approximation. We show how this problem is linked with the notions of weighted ...
The Effects of Collaborative Text Reconstruction on Form 4 Pupils’ Narrative Writing
(Universidad del Zulia, 2019)
Normative Reconstruction and the Hermeneutics of Recognition
(Universidade Estadual de Campinas, 2017)
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 ...
