Utilization of motion capture techniques is becoming more popular in the pipeline of articulated character animation. Based upon captured motion data, defining accurate joints position and joints orientation for the movement of a hierarchical human-like character without using a pre-defined skeleton is still a potential concern for motion capture studio. In this paper, we present a method for a...

A class of motion estimation VLSI architectures is presented which has been developed for the use in studio quality MPEG2 encoders. A new, fast motion estimation algorithm is applied which exploits both, temporal and spatial redundancies in motion vector fields and delivers near full search quality on large search windows. The proposed architectures are MIMD based, scalable both on chip and sys...

On the walls of the Museum there hangs a picture symbolic of one of the strangest phenomena in the history of modern art. It shows five painters gathered in a studio. One is commenting on a drawing by a second, while the other three look up from their work to listen. Painted in London during 1765 by the Pennsylvaniaborn portraitist Matthew Pratt, the canvas was exhibited a year later at the Soc...

Digital signal processing within digital televisions (DTVs) has advanced significantly, resulting in improved picture and audio quality. Further improvements in DTV technology over the next several years will continue to enhance the quality, but the largest gains in the HD video experience will be achieved by improving the A/V source received by the DTV. The video source, for example, is a high...

Modelling software using the Unified Modelling Language (UML) also for embedded real-time systems (ERS) becomes more and more popular since the complexity of these systems increases as well as the pressure of short time-to-market timescales. These notes will introduce some extensions to the UML notation implemented in the CASE-tool Real-time Studio, their motivation and their integration with t...
