High accuracy geometric Hermite interpolation [PDF]

open access: yesComputer Aided Geometric Design, 1987
In natürlicher Verallgemeinerung der Hermiteschen Standardinterpolation werden für parametrisierte ebene Kurven interpolierende kubische Splines p(i) bestimmt. Dabei sind die Knotenpunkte und in jedem Knotenpunkt Tangente und Krümmung vorgeschrieben. Die Komponenten von p(i) sind kubische Polynome auf den Parameterintervallen \((i,i+1)\).

The Significance of Cross-Sectional Shape Accuracy and Non-Linear Elasticity on the Numerical Modelling of Cerebral Veins under Tensile Loading

open access: yesBiology, 2023
Traumatic brain injury (TBI) is a serious global health issue, leading to serious disabilities. One type of TBI is acute subdural haematoma (ASDH), which occurs when a bridging vein ruptures. Many numerical models of these structures, mainly based on the

Current Concept of Geometrical Accuracy [PDF]

open access: yesResearch Papers Faculty of Materials Science and Technology Slovak University of Technology, 2014
Abstract Within the solving VEGA 1/0615/12 research project "Influence of 5-axis grinding parameters on the shank cutter´s geometric accuracy", the research team will measure and evaluate geometrical accuracy of the produced parts. They will use the contemporary measurement technology (for example the optical 3D scanners).

Integrating Stereo Images and Laser Altimetry Points Derived from the Same Satellite for High-Accuracy Stereo Mapping

open access: yesRemote Sensing, 2023
At present, some mapping satellites, such as GaoFen-7 and ZiYuan3-03, are equipped with both optical stereo cameras and laser altimeters that can synchronously obtain stereo images and sparse ground laser altimetry points (LAPs).

Overviews of Optimization Techniques for Geometric Estimation [PDF]

open access: yes, 2013
We summarize techniques for optimal geometric estimation from noisy observations for computer vision applications. We first discuss the interpretation of optimality and point out that geometric estimation is different from the standard statistical ...
