Providing efficient access to the huge amounts of existing medical imaging data is a highly relevant but challenging problem. In this paper, we present an effective method for content-based image retrieval (CBIR) of anomalies in medical imaging data, based on similarity of local 3D texture. During learning, a texture vocabulary is obtained from training(More)
Framed Slotted ALOHA (FSA) is an anti-collision technique in current and future standards of RF-ID systems, as in ISO/IEC CD 18000-6. The number of tags present in the field is a crucial parameter to apply FSA algorithms in an optimal manner. Therefore, a lot of effort is spent on the estimation of this parameter and a range of different estimation(More)
In modern designs for heterogeneous systems with their extreme requirements on power consumption, execution time, silicon area and time-to-market, the HW/SW partitioning problem belongs to the most challenging ones. Usually its formulation, based on task or process graphs with complex communication models, is intractable. Moreover most partitioning problems(More)
CASEPORT 1 makes available extensive collections of medical cases from various distributed first rank case-based e-learning systems to teachers, students and physicians in Germany. By unifying content from various sources, a critical mass for the integration of online case-based courses into undergraduate and postgraduate medical contexts is provided. To(More)
PURPOSE This article reports the user-oriented evaluation of a text- and content-based medical image retrieval system. User tests with radiologists using a search system for images in the medical literature are presented. The goal of the tests is to assess the usability of the system, identify system and interface aspects that need improvement and useful(More)
The Kernighan/Lin graph partitioning heuristic, also known as min-cut, has been enhanced over decades and successfully adopted for circuit partitioning. During last years extended versions have been developed to address functional partitioning as it is needed to solve the much investigated co-design problem of partitioning a system’s coarse-grained(More)
