Telepresence systems use 3D techniques to create a more natural human-centered communication over long distances. This work concentrates on the analysis of latency in telepresence systems where acquisition and rendering are distributed. Keeping latency low is important to immerse users in the virtual environment. To better understand latency problems and to(More)
The selectable marker cyanamide hydratase/cyanamide was successfully used to generate transgenic potato plants from the cultivars Russet Burbank, Ranger Russet, Bintje, Desiree, Kardal and Pentland Dell. Up to 3,000 transgenics per person per year were produced. The efficiency of transgenic production varied among cultivars, and was in general 2–3 times(More)
Depth cameras are increasingly used for tasks such as 3-D reconstruction, user pose estimation, and human-computer interaction. Depth-camera systems comprising multiple depth sensors require careful calibration. In addition to conventional 2-D camera calibration, depth correction for each individual device is necessary. In this paper, we present a new way(More)
Systems for multi-camera telepresence utilizing Large High-Resolution Displays (LHRDs) face the problem of generating large amounts of dynamic data. These data have to be processed at the local capture site, aggregated from different nodes locally, possibly processed again, transmitted to a remote site, and processed further. Since resources are limited a(More)
