Overview of a New Reconstruction Method to Map the Ionosphere at the Brazilian Region
(Inst Navigation, 2018-01-01)
Three-dimensional ionospheric reconstruction at the Brazilian area has been a continuous challenge due to the high ionospheric variability and lack of data in the region. Many efforts have been conducted to overcome these ...

Twofold adaptive partition of unity implicits
(SPRINGER, 2008)
Partition of Unity Implicits (PUI) has been recently introduced for surface reconstruction from point clouds. In this work, we propose a PUI method that employs a set of well-observed solutions in order to produce geometrically ...
Implementação de algoritmos de reconstrução de imagem para tomografia óptica
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia de Controle e AutomaçãoUTFPR, 2017-02-16)
This research shows an abridgement of several image reconstruction techniques used in tomography. It also seeks to perfect the Matrix of Weights – essential element utilised in image reconstruction algebraic techniques – ...
Development and applications of three-dimensional gamma ray tomography system using ray casting volume rendering techniques
(Sociedade Brasileira de Física, 2005-09-01)
Computed Tomography (CT) has made possible visualization of physical structures in the interior of an object in their real relative spatial position and orientation. Another important contribution of CT is to greatly improve ...

Parametric curve reconstruction from point clouds using minimization techniques
(2013-01-01)
Curve reconstruction from noisy point samples is central to surface reconstruction and therefore to reverse engineering, medical imaging, etc. Although Piecewise Linear (PL) curve reconstruction plays an important role, ...

Estimation of the temperature of flame with asymmetric profile
(SPIE, 2014-03)
The large number of projections needed for tomographic reconstruction makes prohibitive the use of algebraic
methods for fast phase object reconstruction. However, for smooth and continuous phase objects, the reconstruction ...
