Supervising the New with the Old: Learning SFM from SFM [PDF]

open access: yes, 2018
Recent work has demonstrated that it is possible to learn deep neural networks for monocular depth and ego-motion estimation from unlabelled video sequences, an interesting theoretical development with numerous advantages in applications. In this paper, we propose a number of improvements to these approaches.

Effects of Feeding Sunflower Meal and Superdosing Phytase on the Production Traits and Nutrient Digestion of Broiler Chickens [PDF]

open access: yesAnimals
Sunflower meal (SFM) is an alternative protein source for poultry. It is locally available and cheap, and its protein is rich in methionine and cystine. The high fibre and phytate content of SFM are, however, limitation factors. The aim of this study was

GEOMONITORING OF A LARGE LANDSLIDE AT THE LÄRCHBERG / MURAU (AUSTRIA) WITH SELECTED GEOSPATIAL TECHNOLOGIES [PDF]

open access: yesActa Geobalcanica, 2021
In April 2001 a rock fall at the Lärchberg-Galgenwald with boulders of several cubic meters in size did occur, which reached until the 50 to 70 m wide apron of the Federal Highway B96.

The Methodological Aspects of Constructing a High-Resolution DEM of Large Territories Using Low-Cost UAVs on the Example of the Sarycum Aeolian Complex, Dagestan, Russia

open access: yesDrones, 2021
Unmanned aerial vehicles (UAV) have long been well established as a reliable way to construct highly accurate, up-to-date digital elevation models (DEM).

The integrative force of political institutions? Direct democracy and voter turnout across ethnic and nativity groups

open access: yesComparative Migration Studies, 2021
Much has been written on the positive effect of direct democracy (initiatives, referendums) on voter turnout. However, we have limited knowledge about potential differential effects on voters belonging to various ethnic groups.

Characterising vent and crater shape changes at Stromboli: implications for risk areas

open access: yesVolcanica, 2021
Active volcanoes are typically subject to frequent substantial topographic changes as well as variable eruption intensity, style and/or directionality. Gravitational instabilities and local accumulation of pyroclasts affect conditions at the active vents,

Video Registration to SfM Models [PDF]

open access: yes, 2014
Registering image data to Structure from Motion (SfM) point clouds is widely used to find precise camera location and orientation with respect to a world model. In case of videos one constraint has previously been unexploited: temporal smoothness. Without temporal smoothness the magnitude of the pose error in each frame of a video will often dominate ...
