The use of rendered images, whether from completely synthetic datasets or from 3D reconstructions, is increasingly prevalent in vision tasks. However, little attention has been given to how the selection of viewpoints affects the performance of rendered training sets. In this paper, we propose a data-driven approach to view set selection. Given a set of example images, we extract statistics des...

The paper presents the development of a simple stochastic model for the noise source of a round turbulent jet. The model is defined on a surface at the rotational/irrotational boundary of the jet and comprises a linear pressure event with random origin and random helical mode. The probability density function for the event’s axial origin is derived from the statistics of coherent structures in ...

by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...

Solar dynamics data, particularly those from the Solar Dynamics Observatory, are now available in a sheer volume that is hard to investigate with traditional visualization tools, which mainly display 2D images. While the challenge of data access and browsing has been solved by web-based interfaces and efforts like the Helioviewer project, the approaches so far only provide 2D visualizations. We...

Numerous studies demonstrated the potential of the magnitude of interferometric coherence |γ| for forest growing stock volume (GSV) estimation in boreal forests. Coherence derived from images acquired under frozen conditions proved to be of specific interest. This also applies to PALSAR coherence, although affected by a comparatively large temporal baseline of at least 46 days. However, when wo...

We present recent developments from a phase variance based motion contrast method of retinal vascular OCT imaging, called phase variance contrast optical coherence tomography (PV-OCT). Using a 25 kHz spectral domain optical coherence tomography (SDOCT) system, the vascular visualization capabilities of this contrast method are demonstrated with composite images created from multiple data sets. ...

in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...
