Socio-environmental impacts of settlement growth under conditions of fostered infill development: A methodological framework for a multicriteria assessment
(2013)The major objective of this study is to analyze socio-environmental conditions under which a sustainable and resource-preserving settlement development can be promoted and to assess respective impacts of greenfield and ... -
Sequential learning using incremental import vector machines for semantic segmentation
(2013)We propose an innovative machine learning algorithm called incremental import vector machines that is used for classification purposes. The classifier is specifically designed for the task of sequential learning, in which ... -
Hierarchical and spatial structures for interpreting images of man-made scenes using graphical models
(2013)The task of semantic scene interpretation is to label the regions of an image and their relations into meaningful classes. Such task is a key ingredient to many computer vision applications, including object recognition, ... -
Automatische Detektion von Krankheiten auf Blättern von Nutzpflanzen
(2013)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 ... -
Ein hierarchischer Ansatz zur Interpration von Gebäudeaufnahmen
(2013)Durch die Fortschritte bei der 3D-Visualisierung von Landschaften und urbanen Räumen in den vergangenen Jahren wächst die Nachfrage nach semantischen und detailgenauen 3D-Stadtmodellen. Die Interpretation von Digitalbildern ... -
Investigations on the Influence of Antenna Near-field Effects and Satellite Obstruction on the Uncertainty of GNSS-based Distance Measurements
(2016-03-31)Antenna near-field effects are one of the accuracy limiting factors on GNSS-based distance measurements. In order to analyse these influences, a measurement campaign at an EDM calibration baseline site with optimum GNSS ... -
Accurate georeferencing of TLS point clouds with short GNSS observation durations even under challenging measurement conditions
(2018-08-29)The accuracy of georeferenced TLS point clouds is directly influenced by site-dependent GNSS effects, deteriorating the accuracy of the ground control point coordinate estimation. Especially under challenging GNSS ... -
Robust Wide-Baseline Stereo Matching for Sparsely Textured Scenes
(2013)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 ... -
Vehicle Tracking and Motion Estimation Based on Stereo Vision Sequences
(2013)<td>In this dissertation, a novel approach for estimating trajectories of road vehicles such as cars, vans, or motorbikes, based on stereo image sequences is presented. Moving objects are detected and reliably tracked in ... -
Visual SLAM from image sequences acquired by unmanned aerial vehicles
(2013)This thesis shows that Kalman filter based approaches are sufficient for the task of simultaneous localization and mapping from image sequences acquired by unmanned aerial vehicles. Using solely direction measurements to ... -
Finding spectral features for the early indentification of biotic stress in plants
(2013)Early detection of biotic stress in plants is vital for precision crop protection, but hard to achieve. Prediction of plant diseases or weeds at an early stage has significant influence on the extent and effectiveness of ... -
Digital filtering algorithms for decorrelation within large least squares problems
(2012)The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ... -
Ein Beitrag zur koordinatengesteuerten Aussaat von Rübenpflanzen mittels Multi-Sensor-System und Filteransatz
(2012)Die Bestandspflege von landwirtschaftlichen Kulturen, maßgeblich geprägt durch die Unkrautkontrolle, wird heutzutage überwiegend mit chemischen Pflanzenschutzmitteln betrieben. Der gestiegene Bedarf an Bioprodukten erfordert ... -
Attributierte Grammatiken zur Rekonstruktion und Interpretation von Fassaden
(2012)Dem Bedarf und Nutzen hoch detaillierter 3D-Stadt- und Gebäudemodelle steht deren aufwendige Erfassung gegenüber. Ist die automatische Ableitung vereinfachter Dachstrukturen aus Luftbildern oder Laseraltimetrie weitestgehend ... -
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012)Die dynamische Ozeantopograpie als Differenz zwischen Meeresoberfläche und dem Geoid reflektiert charakteristische Merkmale der Ozeanzirkulation und stellt als gemessene Größe somit eine bedeutende Eingangsgröße in ... -
Lecture Notes from the Summer School of DFG SPP1257 Global Water Cycle: September 12-16, 2011, [Mayschoss/Ahr]
(2013)In 2006, the German Research Association DFG had established the coordinated Priority Program <i>SPP1257 Mass distribution and Mass Transport in the Earth System</i>. According to DFG’s philosophy, SPP’s are meant to enable ... -
Die Anerkennung und Feststellung von Grundstücksgrenzen: Ein Beitrag zur Entwicklung des Liegenschaftskatasters im Lande Nordrhein-Westfalen in Vergangenheit Gegenwart und Zukunft
(2012)Das Eigentum am Grund und Boden wird im Grundbuch und im Liegenschaftskataster nachgewiesen und dokumentiert. Die aufgrund der historischen Entstehung und Entwicklung inhomogenen Nachweise des Liegenschaftskatasters sind ... -
Separablity of deformations and measurements noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
(2012)The separation of the deformations and measurement noise of GPS coordinate time series and accuracy improvement of GPS real-time coordinates are major aspects of the thesis. In order to reduce the influence of the colored ... -
An improved global gravity field model of the Earth derived from reprocessed GOCE observations with the time-wise approach
(2019)ESA's dedicated gravity field mission GOCE (Gravity field and steady-state Ocean Circulation Explorer) successfully completed its science operations in 2013 as the first Earth Explorer mission in orbit. In 2014, the fifth ... -
An improved global gravity field model from the GOCE mission: the time-wise release 6 model
(2019)The Gravity field and steady-state Ocean Circulation Explorer (GOCE) completed its science mission to observethe Earth’s gravity field in 2013. From the collected observations, gravity gradients and tracking ...
