Collaborative Working Environments: Group Needs Approach to Designing Systems for Supporting Spatially Distributed Groups
(2011-02-24)
Collaboration in spatially distributed groups requires technological support for mediating collaborative activities and members’ interactions over time and distance. Technology provides multiple tools for supporting ...
Robust Wide-Baseline Stereo Matching for Sparsely Textured Scenes
(2011-08-19)
The task of wide baseline stereo matching algorithms is to identify corresponding elements in pairs of overlapping images taken from significantly different viewpoints. Such algorithms are a key ingredient to many computer ...
Automatische Detektion von Krankheiten auf Blättern von Nutzpflanzen
(2011-12-21)
In dieser Arbeit wird ein neuartiges, automatisches Verfahren zur Detektion von Krankheiten auf Blättern von Nutzpflanzen vorgestellt. Die Anwendung von Mustererkennungsverfahren zur Detektion von Blattkrankheiten ist noch ...
Grouping Uncertain Oriented Projective Geometric Entities with Application to Automatic Building Reconstruction
(2007)
The fully automatic reconstruction of 3d scenes from a set of 2d images has always been a key issue in photogrammetry and computer vision and has not been solved satisfactory so far. Most of the current approaches match ...
3D-Stadtmodellierung auf heterogenen Ausgangsmodellen mittels evolutionärer Algorithmen
(2007)
Die vorliegende Arbeit beschreibt ein neuartiges Verfahrens zur flexiblen und effizienten 3D-Stadtmodellierung im Kontext der Verfügbarmachung von 3D-Stadtmodellen. Ausgangspunkt ist die Heterogenität existierender und ...
Methodische Probleme bei der Erstellung von Unkrautverteilungskarten mit Geoinformationssystemen (GIS)
(2005)
Die vorliegende Arbeit befaßt sich mit den methodischen Problemen, die bei der Erstellung von Unkrautverteilungskarten mit Geoinformationssystemen (GIS) auftreten können. Im Vordergrund steht dabei die Frage nach der ...
Statistical relational learning of semantic models and grammar rules for 3D building reconstruction from 3D point clouds
(2016-11-04)
Formal grammars are well suited for the estimation of models with an a-priori unknown number of parameters such as buildings and have proven their worth for 3D modeling and reconstruction of cities. However, the generation ...
Resilience, collapse and reorganization of a rangeland socio-ecological system in South Africa
(2016-05-24)
Communal rangelands in semi-arid areas are complex socio-ecological systems (SES). Their complexity arises from non-linear feedbacks between the social- and the ecosystem. To understand the social system requires tackling ...
Robot Navigation Beyond Planning the Shortest Path
(2021-04-16)
Over the last decade, the demand for autonomous mobile robots has been growing continuously. Applications range from mobile manipulators operating on factory floors to autonomous cars driving in urban environments. A common ...
Graph-based Sliding Window Localization and Map Refinement for Automated Vehicles
(2021-10-12)
Localization is an essential task in automated driving and advanced driver assistance systems. The precise location of a vehicle is required for extracting information from a map about the vehicle's environment. The map ...
