T1 - Entlassmanagement im Krankenhaus T2 - Dienstleistungsmanagement im Krankenhaus II: Prozesse, Produktivität, Diversität N2 - Krankenhäuser sind ständig auf der Suche nach Verbesserungs- und Optimierungspotenzialen im Kosten- und Erlösbereich. Die Prozessoptimierung gehört hierbei zu einem beliebten Instrument; als Optimierungsobjekt schälen sich immer mehr Querschnittsprozesse heraus. Das im Folgenden beschriebene Projekt untersuchte in Kooperation mit mehreren kommunalen Häusern im Rahmen eines strukturierten Benchmarkings, ob die Anstrengungen im Prozess „Stationäre Entlassung“ im Vergleich mit anderen Häusern ausreichten oder ob noch weiteres Potenzial vorhanden war. Das Neue hierbei war die detaillierte Modellierung der Prozesse und die Analyse anhand von Kennzahlenvergleichen.

T1 - Establishing score equivalence of the Functional Independence Measure (FIM™) motor scale and the Barthel Index, utilising the International Classification of Functioning, Disability and Health (ICF) and Rasch Measurement Theory JF - Journal of Rehabilitation Medicine N2 - Introduction: Two widely used outcome measures to assess functioning in neurological rehabilitation are the Functional Independence Measure (FIM™) and the Barthel Index. The current study aims to establish the equivalence of the total score of the FIM™ motor scale and the Barthel Index through the application of the International Classification of Functioning, Disability and Health, and Rasch measurement theory. Methods: Secondary analysis of a large sample of patients with stroke, spinal cord injury, and multiple sclerosis, undergoing rehabilitation was conducted. All patients were assessed at the same time on both the FIM™ and the Barthel Index. The International Classification of Functioning, Disability and Health Linking Rules were used to establish conceptual coherency between the 2 scales, and the Rasch measurement model to establish an exchange of the total scores. Results: Using the FIM™ motor scale, items from both scales linked to the International Classification of Functioning, Disability and Health d4 Mobility or d5 Self-care chapters. Their co-calibration satisfied the assumptions of the Rasch model for each of 3 diagnostic groups. A ceiling effect was observed for the Barthel Index when contrasted against the FIM™ motor scale. Conclusion: Having a Rasch interval metric to transform scores between the FIM™ motor scale and Barthel Index is valuable for monitoring functioning, meta-analysis, quality audits and hospital benchmarking.

T1 - Nonlinear Refinement of Camera Parameters using an Endoscopic Surgery Robot T2 - Proceedings of IAPR Conference on Machine Vision Applications (MVA) N2 - We present an Approach for non linea roptimization of the parameters of an endoscopic camera mounted on a surgery robot. The goal is to generate a depth map for each image in order to enhance the quality of medical light fields. The pose information provided by the robot is used as an initialization, where especially the orientation isi naccurate. Refinement of intrinsic and extrinsic camera parameters is performed by minimizing the back-projectionerror of 3-D points that are reconstructed by triangulation from image Feature stracked over an image sequence. Optimization of the camera parameters results in an enhancement of Rendering Quality in two ways: More accurate parameters lead to better interpolation as well as to better depth maps for approximating the scenegeometry.

T1 - Dense Disparity Maps in Real-Time with an Application to Augmented Reality T2 - Proceedings Sixth IEEE Workshop on Applications of Computer Vision (WACV 2002), pages 225-230, Orlando, FL USA N2 - This work presents a technique for computing dense disparity maps from a binocular stereo camera system. The methods are applied in an Augmented Reality setting for combining real and virtual worlds with proper occlusions. The proposed stereo correspondence technique is based oil area matching and facilitates an efficient strategy by using the concept of a three-dimensional similarity accumulator whereby occlusions are detected and object boundaries are extracted correctly. The main contribution of this paper is the way we fill the accumulator using absolute differences of images and computing a mean filter on these difference images. This. is. where the main advantages of the accumulator approach can be exploited, since all entries can be computed in parallel and thus extremely efficient. Additionally, we-perform an asymmetric correction step and a post-processing of the disparity maps that maintains object edges.

T1 - Using Quaternions for Parametrizing 3D Rotations in Unconstrained Nonlinear Optimization T2 - Vision, Modeling, and Visualization 2001, pages 399-406, Stuttgart, Germany N2 - In this paper we address the problem of using quaternions in unconstrained nonlinear optimization of 3-D rotations. Quaternions representing rotations have four elements but only three degrees of freedom, since they must be of norm one. This constraint has to be taken into account when applying e.g. the Levenberg-Marquardt algorithm, a method for unconstrained nonlinear optimization widely used in computer vision. We propose an easy to use method for achieving this. Experiments using our parametrization in photo grammetric bündle -adjustment are presented at the end of the paper.

T1 - Placing Arbitrary Objects in a Real Scene Using a Color Cube for Pose Estimation T2 - Pattern Recognition, 23rd DAGM Symposium N2 - We describe an Augmented Reality system using the corners of a color cube for camera calibration. In the augmented image the cube is replaced by a computer generated virtual object. The cube is localized in an image by the CSC color segmentation algorithm. The camera projection matrix is estimated with a linear method that is followed by a nonlinear refinement step. Because of possible missclassifications of the segmented color regions and the minimum number of point correspondences used for calibration, the estimated pose of the cube may be very erroneous for some frames; therefore we perform outlier detection and treatment for rendering the virtual object in an acceptable manner.
