Tv Regularization, Steffen Remmele, Madeleine Seel, Jürgen Hesser
Abstract. Fluorescence microscopy has become an important tool in biological and medical sciences for imaging thin specimen, even living ones. Due to Out-of-focus blurring and noise the acquired...
Fajardo Silva, Raul S., Hesser, Jürgen, Männer, Reinhard
The early fault analysis is mandatory for safety critical systems, which are required to operate safely even on the presence of faults. System design methodologies tackle the early design and...
Real-Time Physiological Simulation and Modeling toward Dependable Patient Monitoring Systems (2009)
We present a novel approach to describe dependability measures for intelligent patient monitoring devices. The strategy is based on using a combination of methods from system theory and real-time...
Motion-based Segmentation and Classification of Video Objects (2008)
Dekan Professor, Referent Professor, Dr. Wolfgang Effelsberg, ...
In this thesis novel algorithms for the segmentation and classification of video objects are developed. The segmentation procedure is based on motion and is able to extract moving objects acquired by...

Volume rendering is a key technique in scientijic visualization that lends itselfto signijicantexploitable parallelism. The high computational demantJs of real-time volurne rendering and continued...
Live-Wires on Edges of Presegmented 2D-Data (2007)
Sebastian König, Dr. Jürgen Hesser
Abstract. In this article we present an extension to the Live-Wire segmentation approach. An automatic preprocessing is done before the interactive segmentation and thus provides an additional level...
Correction of C-Arm Projection Matrices by (2007)
Rigid Registration Of, Ulrich Müller, Stefan Bruck, Jürgen Hesser, Reinhard Männer
ls around these sample points. From this approximation we obtain an estimation of the histogram distribution and thus the mutual information. Then a local optimization allows to find a set of locally...
Robust Head Tracking for fMRI and MEG (2007)
Dennis Maier, Jürgen Hesser, Reinhard Männer
In this work we present a comparison of two methods for tracking patients in imaging systems, whereby we concentrate on functional Magnetic Resonance Imaging (fMRI) and Magneto-Encephalography (MEG)....
CathI – Training system for PTCA A step closer to reality (2007)
Carsten Bienek, Dzmitry Stsepankou, Dr. Jürgen Hesser
Abstract: The number of minimally invasive cardiological interventions has increased over the last few years and therefore computer based training systems find growing interest. They offer a better...
Analysis and Prediction of Helix Shift Errors in Homology Modeling (2006)
Bock, Christoph, Hesser, Jürgen
High sequence identity between two proteins (e.g. > 60%) is a strong evidence for high structural similarity. However, internal shifts in one of the two proteins can sometimes give rise to...

Dense Disparity Maps Respecting Occlusions and Object (2003)
Dennis Maier, Andreas Rößle, Jürgen Hesser, Reinhard Männer, Lehrstuhl Für Informatik
Abstract. In this work, we present substantial enhancements to solve the stereo correspondence problem using a minimization and regularization formulation with a partial differential equations...
Dennis Maier, Jürgen Hesser, Reinhard Männer
The Iterative Closest Point (ICP) algorithm is widely used to register two roughly aligned surfaces. Its most expensive step is the search for the closest point. Many efficient variants have been...

Calculating dense disparity maps from color stereo images, an efficient implementation (2002)
Karsten Mühlmann, Dennis Maier, Jürgen Hesser, Reinhard Männer
Abstract — This paper presents an efficient implementation for correlation based stereo. Research in this area can roughly be divided in two classes: improving accuracy regardless of computing time...

A divide and conquer approach to fast loop modeling (2002)
Tosatto, Silvio C.E., Bindewald, Eckart, Hesser, Jürgen, Männer, Reinhard
We describe a fast ab initio method for modeling local segments in protein structures. The algorithm is based on a divide and conquer approach and uses a database of precalculated look-up tables,...
Interactive Segmentation and Visualization of Volume Data Sets (1997)
Gerald Kühne, Thomas Günther, Christoph Poliwoda, Jürgen Hesser, Christof Reinhart, Reinhard Männer
A two-stage methodology for interactive segmentation of volume data sets is presented in this paper. In the first stage (presegmentation) a 3D watershed transformation is used for segmenting the data...
