We focus on data gathering problems in energy-constrained wireless sensor networks. We study store-and-gather problems where data are locally stored on the sensors before the data ...
Abstract. Differential motion estimation is based on detecting brightness changes in local image structures. Filters approximating the local gradient are applied to the image seque...
This paper introduces a design tool and its associated procedures for determining the sensitivity of outputs in a digital signal processing design to small errors introduced by ro...
MPEG-4 Fine Granularity Scalability (FGS) provides bandwidth adaptation and error resilience features for streaming applications. In this paper. by estimating the required computa...
The use of Shared Virtual Environments is growing in areas such as multi-player video games, military and industrial training, and collaborative design and engineering. At the sam...
