Mixed 2D/3D Perception for Autonomous Robots in Unstructured Environments
Autonomous robots in real world applications have to deal with a complex 3D environment, but are often equipped with standard 2D laser range finders (LRF) only. By using the 2D LRF for both, the 2D localizatio...

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...

An Evaluation of Open Source SURF Implementations
SURF (Speeded Up Robust Features) is a detector and descriptor of local scale- and rotation-invariant image features. By using integral images for image convolutions it is faster to compute than other state-of...

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...

Wavelet-Based Inpainting for Object Removal from Image Series
We propose several algorithmic extensions to inpainting that have been proposed to the spatial domain by other authors and apply them to an inpainting technique in the wavelet domain. We also introduce a new m...

Vessel Enhancement in 2D Angiographic Images
In this paper we extend the Frangi filter[1] to recognize edges and do not enhance them. We give a theoretical framework for optimal scale selection and choice of the free parameters. We discuss discretization de...

Adapting Object Recognition across Domains: A Demonstration
High-level vision systems use object, scene or domain specific knowledge to interpret images. Unfortunately, this knowledge has to be acquired for every domain. This makes it difficult to port systems from one...

Appearance-Based Statistical Object Recognition by Heterogeneous Background and Occlusions
In this paper we present a new approach for the localization and classification of 2-D objects that are situated in heterogeneous background or are partially occluded. We use an appearance-based approach and m...
