3D Pose Detection for Articulated Vehicles
The knowledge about relative poses within a tractor/trailer is a vital prerequisite for kinematic modeling and trajectory estimation. In case of autonomous vehicles or systems, for example, the monitoring ...

Extended Investigations on Skeleton Graph Matching for Object Recognition
Shape similarity estimation of objects is a key component in many computer vision systems. In order to compare two shapes, salient features of a query and target shape are selected and compared with each other...

Texture-Based Text Detection in Digital Images with Wavelet Features and Support Vector Machines
In this paper we propose to combine region-based and texture-based approaches for text detection in digital images. Our solution is based on a cascade filtering of image regions. First, we apply heuristic filt...

A Generic Approach to the Texture Detection Problem in Digital Images
In this paper, we describe our solution to the marker detection problem in digital images. In order to keep our investigations as general as possible, our approach has not been developed in an application-driv...

Stable Map** Using a Hyper Particle Filter
Often Particle Filters are used to solve the SLAM (Simultaneous Localization and Map**) problem in robotics: The particles represent the possible poses of the robot, and their weight is determined by checkin...

Verbesserte GPS-Positionsschätzung mit IP-transportierten Korrekturdaten für autonome Systeme im Outdoor-Bereich
Für autonome Systeme im Outdoor-Bereich können zur groben Selbstlokalisation GPS-Positionsdaten genutzt werden. Leider sind diese Positionsdaten bedingt durch verschiedene Fehlerquellen recht ungenau. Eine Mög...
