Recent advances in augmented reality and portable systems bring us closer to the introduction of such advanced technologies in everyday routine of cultural heritage sites, providing an extremely helpful means of disseminating and communicating information to the visitors of such sites. Portable multimedia guides are already a reality, while fixed-position(More)
This paper describes ongoing research concerning interactive volume visualization coupled with tools for volumetric analysis. To establish an easy to use application, the three-dimensional-visualization has been embedded in a state of the art teleradiology system, where additional functionality is often desired beyond basic image transfer and management.(More)
Whether or not a computerized system enhances the conditions of work in the application domain, very much demands on the user interface. Graphical user interfaces seem to attract the interest of the users but mostly ignore some basic rules of visual information processing thus leading to systems which are difficult to use, lowering productivity and(More)
The operability of a liver tumour depends on its three-dimensional relation to the intrahepatic vascular trees which define autonomously functioning liver (sub-)segments. The aim of our study was to establish a computer-based three-dimensional volumetric operation planning system for the liver. Methods: Using data from routine helical CT scans the three(More)
Operability of a liver tumor depends on its three dimensional relation to the intrahepatic vascular trees as well as the volume ratio of healthy to tumorous tissue. Precise operation planning is complicated by anatomic variability and distortion of the vascular trees by the tumor or preceding liver resections. We have developed a computer based 3D virtual(More)
The new generation of television viewers is currently being confronted and becoming acquainted with a series of technological developments in the realm of consumer electronics and gaming that raise their expectations for similar advances in TV broadcasts. The MELISA platform aims at the crossmedia broadcasting of sports events featuring interactive(More)
This paper presents an FPGA-based machine vision implementation for flow detection on Lab-on-Chip (LoC) experiments. The proposed machine vision system is designed to provide real-time information to the LoC user about the state of the flows (flow coordinates and points of interest) as well as input to the LoC controller. It is uniquely designed to(More)
