The degree of visibility of any kind of stimulus is largely determined by the background on which it is shown, a property commonly known as masking. Many psychophysical experiments have been carried out to date to understand masking of sinusoids or Gabor t ...
Text embedded in images and videos represents a rich source of information for content-based indexing and retrieval applications. In this paper, we present a new method for localizing and recognizing text in complex images and videos. Text localization is ...
In this paper, we present full-reference as well as no-reference metrics for typical JPEG 2000 compression artifacts, namely blur and ringing. These metrics are based on an analysis of the edges and adjacent regions in an image. Their perceptual significan ...
This paper describes the design, implementation, and performance of a simple yet powerful Application Programming Interface (API) for providing extended services in a proxy cache. This API facilitates the development of customized content adaptation, conte ...
In this paper, we present a personalized multimedia content delivery system dealing with both user preferences and terminal/network capabilities. In order to ease interoperability with third-party applications, content annotation, user preferences handling ...
This technical report provides an evaluation of several possible languages and semantic formalisms that could be used in agent communication to play the role of a content language in the EU Agentcities.RTD project. The conclusions and background informatio ...
Since the mid 1990s, network and systems management has steadily evolved from a centralized paradigm, where all the management processing takes place in a single management station, to distributed paradigms, where management is distributed over a potential ...
We consider cluster-based network servers in which a front-end directs incoming requests to one of a number of back-ends. Specifically, we consider content-based request distribution: the front-end uses the content requested, in addition to information abo ...
With the growing ubiquity and mobility of multimedia-enabled devices, universal multimedia access (UMA) is emerging as one of the important components for the next generation of multimedia applications. The basic concept underlying UMA is universal or seam ...
Over the past few years, network management has steadily evolved from a centralized model, where all the management processing takes place on a single network management station, to distributed models, where management is distributed over a number, potenti ...
