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

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

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