In this paper we present a security framework for executing foreign programs, called helpers, on a Pocket Companion: a wireless hand-held computer. A helper program as proposed is...
Piecewise constant and piecewise smooth Mumford-Shah (MS) models have been widely studied and used for image segmentation. More complicated than piecewise constant MS, global Gaus...
In this paper, we present a system architecture that allows users to interact with embedded systems located in their proximity using Smart Phones. We have identified four models o...
We present 3D video fragments, a dynamic point sample framework for real-time free-viewpoint video. By generalizing 2D video pixels towards 3D irregular point samples we combine t...
—Popular Internet services are hosted by multiple geographically distributed datacenters. The location of the datacenters has a direct impact on the services’ response times, c...
