historical images image orientation feature matching descriptor matching quadrilaterals geometry
2018/3/30
This contribution shows an approach to match historical images from the photo library of the Saxon State and University Library Dresden (SLUB) in the context of a historical three-dimensional city mod...
Indoor Modelling Benchmark for 3D Geometry Extraction
Indoor 3D Modelling Benchmark Terrestrial Laser Scanning Segmentation Reconstruction
2014/6/30
A combination of faster, cheaper and more accurate hardware, more sophisticated software, and greater industry acceptance have all laid the foundations for an increased desire for accurate 3D parametr...
Extracting Rail Track Geometry from Static Terrestrial Laser Scans for Monitoring Purposes
Terrestrial laser scanning (TLS) static deformation monitoring rail track geometry extraction
2014/6/30
This paper presents the capabilities of detecting relevant geometry of railway track for monitoring purposes from static terrestrial laser scanning (TLS) systems at platform level. The quality of the ...
We show how to calculate the first- and second-order statistics of the scattered fields for an arbitrary intensity coherent-state light field interacting with a two-level system in a...
A geometry and optical property inspection system for automotive glass based on fringe patterns

Understanding the dispersion of coaxial plasmonic structures through a connection with the planar metal-insulator-metal geometry
coaxial plasmonic structures planar metal-insulator-metal geometry
2009/8/10
We elucidate the dispersion behavior of deep-subwavelength propagating modes in coaxial plasmonic structures by making an explicit connection with the planar metal-insulator-metal geometry. We provide...
Geometry-controlled droplet generation in head-on microfluidic devices
Geometry-controlled droplet generation microfluidic devices
2008/7/29
We investigated the generation of droplets in a head-on microfluidic device operated with the two identical channels as inlets and the “long leg” as a constriction channel leading to a wider outlet se...
Omnidirectional resonance in a metal–dielectric–metal geometry
Omnidirectional resonance metal–dielectric–metal geometry
2004/8/11
We show that a planar metallic microcavity structure can exhibit an omnidirectional resonance, i.e.,a resonance for which the resonance wavelength is independent of the incidence angle of light. The s...
All-optical transistor action with bistable switching in a photonic crystal cross-waveguide geometry
All-optical transistor action bistable switching photonic crystal cross-waveguide geometry
2003/8/11
We demonstrate all-optical switching action in a nonlinear photonic crystal cross-waveguide geometry with instantaneous Kerr nonlinearity, in which the transmission of a signal can be reversibly switc...
