3D Scene Segmentation and Object Tracking in Multiocular Image Sequences (2009)
Joachim Schmidt, Christian Wöhler, Lars Krüger, Tobias Gövert, Christoph Hermes
Abstract. In this contribution we describe a vision-based system for the 3D detection and tracking of moving persons and objects in complex scenes. A 3D point cloud of the scene is extracted by a...
3D Action Recognition and Long-term Prediction of Human Motion (2009)
Markus Hahn, Lars Krüger, Christian Wöhler
Abstract. In this contribution we introduce a novel method for 3D trajectory based recognition and discrimination between different working actions and long-term motion prediction. The 3D pose of the...
Markus Hahn, Lars Krüger, Christian Wöhler
In this contribution we introduce the Shape Flow algorithm (SF), a novel method for spatio-temporal 3D pose estimation of a 3D parametric curve. The SF is integrated into a tracking system and its...
Feature and Viewpoint Selection for Industrial Car Assembly (2008)
Dirk Stößel, Marc Hanheide, Gerhard Sagerer, Lars Krüger
Abstract. Quality assurance programs of today’s car manufacturers show increasing demand for automated visual inspection tasks. A typical example is just-in-time checking of assemblies along...
Tracking of Human Body Parts using the Multiocular Contracting Curve Density Algorithm (2008)
Markus Hahn, Lars Krüger, Christian Wöhler
In this contribution we introduce the Multiocular Contracting Curve Density algorithm (MOCCD), a novel method for fitting a 3D parametric curve. The MOCCD is integrated into a tracking system and its...
Model based object classification and localisation in multiocular images (2007)
In this thesis various approaches to object recognition are investigated, mainly recorded by multiocular imaging systems. The strengths and weaknesses of the approaches are analysed. Several...
3D Scene Segmentation and Object Tracking in Multiocular Image Sequences (2007)
Schmidt, Joachim, Wöhler, Christian, Krüger, Lars, Gövert, Tobias, Hermes, Christoph
In this contribution we describe a vision-based system for the 3D detection and tracking of moving persons and objects in complex scenes. A 3D point cloud of the scene is extracted by a combined...

Annika Kuhl, Christian Wöhler, Lars Krüger, Horst-michael Groß
Abstract. We propose a method for combining geometric and realaperture methods for monocular 3D reconstruction of static scenes at absolute scales. Our algorithm relies on a sequence of images of the...
Für die autonomen Parvoviren MVMp und H-1 Virus wurden onkotrope und onkolytische Eigenschaften beschrieben, also eine präferentielle Replikation dieser Viren mit einhergehender Lyse in...

Infactory calibration of multiocular camera systems (2004)
Lars Krüger, Christian Wöhler, Er Würz-wessel, Fridtjof Stein
A complete framework for automatic calibration of camera systems with an arbitrary number of image sensors is presented. This new approach is superior to other methods in that it obtains both the...
Training of Classifiers Using Virtual Samples Only (2004)
Annika Kuhl, Lars Krüger, Christian Wöhler, Ulrich Kreßel
This paper describes the training of classifiers entirely based on virtual images, rendered by a ray-tracing software. Two classifiers, a support vector machine and a polynomial classifier, are...
Model based multiview active contours for quality inspection (2004)
In this paper, 3D parametric active contours are used to segment contours of flexible objects. The contour is a 3D curve or a "weak " model supplying information about the object contour....
