Saliency detection aims to detect the most attractive objects in images, which has been widely used as a foundation for various multimedia applications. In this paper, we propose a novel salient object detection algorithm for RGB-D images using center-dark channel prior. First, we generate an initial saliency map based on a color saliency map and a depth saliency map of a given RGB-D image. The...

Latency performance is enhanced in Network-on-Chips using a variety of techniques, among which virtual channel approach is one of the most widely used. With virtual channels, high priority packets can pre-empt low priority packets but this can cause starvation of low priority packets which can be un-necessary in many situations. With this paper we present an improvement on the classical virtual...

ÐThe problem of allocating high-volume multimedia files on a virtual circuit network with the objective of maximizing channel throughput (and minimizing data transmission time) is addressed. The problem is formulated as a multicommodity flow problem. We present both the optimal and suboptimal solutions to the problem using novel approaches. Index TermsÐFile allocation, virtual circuit, cut, max...

In this paper we present structuring concepts for networked systems management. The concepts mainly deal with organizing and structuring management systems by introducing building blocks (called domains) and managed resources abstract representations (called shields). Domains are used as a means for grouping resources according to different criteria and shields are used, within domains, to reve...

This paper describes the haptic rendering of a virtual environment by drawing upon concepts developed in the area of teleoperation. A four-channel teleoperation architecure is shown to be an e ective means of coordinating the control of a new 3-DOF haptic interface with the simulation of a virtual dynamic environment.

Cooperation in ad hoc networks cannot be taken for granted when nodes belong to distinct authoritative domains. In this paper we present Cashflow, a virtual currency system to motivate nodes to participate in ad hoc networks and to prevent selfishness. This system is different to previously proposed virtual currency systems in that it uses a channel concept for data transmission as well as a ma...

This paper describes an interactive multi-channel multiuser networked system for real-time composition and immersive performance built using a modified version of the Quake III gaming engine. By tracking users’ positional and action data within a virtual space, and by streaming that data over a network using OSC messages formatted as UDP packets to a multi-channel Pure Data patch, actions in vi...

Power transformers sometimes locate in an enclosed room with an opening surface for the ventilation purpose. Under these situations, most noise radiates out from the opening, so a virtual sound barrier can be built to suppress the sound radiation outside by employing a multiple-channel active noise control system. Based on the sound radiation model of indoor monopoles, the noise reduction perfo...
