A Dynamic Programming (DP) based algorithm that achieves real-time, high quality stereo-matching is presented. A special coarse to fine approach as well as the MMX based assembler implementation mainly contribute to the reached computation speed. A novel vertical smoothing approach by re-integrating paths inside the DP matching allows the avoidance of noisy(More)
This paper describes a system for dynamic simulation of linked rigid bodies in real-time. The system was developed to simulate mechanical behaviour in VR applications. An extension for a 3D modelling tool was developed which provides the possibility to model a VR scene including the geometries and mechanical parameters of all rigid bodies and the properties(More)
A simplified numeric method for the mechanical simulation in virtual realty systems Abstract Present virtual reality systems (VR-systems) must still extended considerably in their functionality to model autonomous mobile robots as interaction-partners. Especially it must be possible to simulate nearly precise the mechanics in the VR-simulation. With this in(More)
We present an interactive, real-time mapping system for use with digital elevation models and remotely sensed multispectral imagery, which aids geoscientists in the creation and interpretation of geologic/neotectonic maps at length scales of 10 m to 1000 km. Our system provides a terrain visualization of the surface of the Earth or other terrestrial planets(More)
Markerless optical motion tracking is still a challenging task; especially applied for interactive environment there real-time is required. Tracking methods based on silhouette extraction seem to have the ability for robust real-time detection. But most background subtraction methods are unable to adapt their background model to the fast changing(More)
