One of the important objectives of business data visualization for decision making is to assist the user in their cognition and recall of prominent features and patterns of data. In this study, we extend Chernoff faces to full-featured animated figures to represent multi-dimensional data. A prototype has been developed that allows the user to easily assign data attributes to figural features as...

Plasmonic gap modes provide the ultimate confinement of optical fields. Demanding high spatial resolution, the direct imaging of these modes was only recently achieved by electron energy loss spectroscopy (EELS) in a scanning transmission electron microscope (STEM). However, conventional 2D STEM-EELS is only sensitive to components of the photonic local density of states (LDOS) parallel to the ...

In many occasions orthophotos in the background of GIS applications enrich their presentation. Often they serve for data capturing. Geometrically such images posses a defined, homogeneous geometry. One produces orthophotos since several decades with ever increasing demands and performance in quality and quantity. However, large-scale city orthophotos using standard algorithms and procedures typ...

We introduce and study a tactic language, Hitac, for constructing hierarchical proofs, known as hiproofs. The idea of hiproofs is to superimpose a labelled hierarchical nesting on an ordinary proof tree. The labels and nesting are used to describe the organisation of the proof, typically relating to its construction process. This can be useful for understanding and navigating the proof. Tactics...

The parallel processing of visual information was studied with penetrating microelectrode arrays. We studied the high-resolution visuotopic organization of cat primary visual cortex, and the encoding of simple visual stimuli by ensembles of ganglion cells in the isolated turtle retina. The high-resolution visuotopic organization of visual cortex is non-conformal. Regions of visual cortex separa...

Understanding climate as a driver of low- to moderate-severity fires in the Montane Cordillera Ecozone Canada is priority given predicted and observed increases frequency severity large due change. We characterised historical fire-climate associations using 14 crossdated fire-scar records tree-ring proxy reconstructions summer drought annual precipitation from region. compared among years when ...

The transition of the powertrain from combustion to electric systems increases demand for reliable copper connections. For such applications, laser welding has become a key technology. Due complexity welding, especially at micro with small weld seam dimensions and short process times, in-line monitoring proven be difficult. By using green wavelength ?=515 nm, benefits an increased absorption, r...

Abstract Surgical navigation-assisted interventions, providing augmented previously acquired image data to support the physician, are routinely used. Visualization techniques like extended reality (XR) promise improvements because desired information can be shown where most suitable. The accuracy of such systems is essential for usability in clinical interventions but lacks research. This work ...

Knowledge-based numeric open caption recognition is proposed that can recognize numeric captions generated by character generator (CG) and automatically superimpose a modified caption using the recognized text only when a valid numeric caption appears in the aimed specific region of a live sportscast scene produced by other broadcasting stations. In the proposed method, mesh features are extrac...

This paper presents a new registration algorithm of 2D color images and 3D geometric models for navigation system of surgical robot. A 2D-3D registration procedure is used to superimpose a tumor model on an endoscopic image precisely, and is therefore indispensable for the surgical navigation system. And thus, the performance of the 2D-3D registration procedure influences directly the usability...
