This paper describes an approach to tracking the global locations of multiple dancers using marker-based motion capture system from only unlabeled 3D marker data for the application of interactive dance. This algorithm is based on the fact that in the presence of multiple people, marker labeling is poor or even infeasible, while reconstruction of the marker 3D coordinates is still reasonable. T...

We generalize the notion of pattern avoidance to arbitrary functions on ordered sets, and consider specifically three scenarios for permutations: linear, cyclic and hybrid, the first one corresponding to classical permutation avoidance. The cyclic modification allows for circular shifts in the entries. Using two bijections, both ascribable to both Deutsch and Krattenthaler independently, we sin...

This paper presents a new polling scheme, that can be used at the Access Point of an IEEE802.11 wireless network as part of the Point Coordination Function, in order to provide guaranteed QoS support of voice traffic. The so called Cyclic Shift polling scheme along with the use of silence detection at the mobile terminals increases the supported number of calls, as a function of the overall rat...

As FPGA densities have increased, the feasibility of using floatingpoint computations on FPGAs has improved. Moreover, recent innovations in FPGA architecture have changed the design tradeoff space by providing new fixed circuit functions which may be employed in floating-point computations. These include high density multiplier blocks and shift registers. This paper evaluates the use of such b...

Laser scanning data has been an important raw source for building model extraction. However, the automatic reconstruction of building model is still a problem. Roof plane Extraction from point cloud is a key step to building reconstruction, which can be easily affected by the noise existed in laser scanning data. It is often difficult to determine which plane a point should belong to when the p...
