Traditional text information–based management and utilization methods can not satisfy application demands of implicit and unstructured agriculture multimedia data. For providing a readable-friendly agriculture science & technology information service, this paper proposes a relation database model oriented multimedia data method, which implements content-based multimedia data search by indexing ...

Distributed multimedia applications are currently being supported by a growing number of services. However, characteristic requirements of these applications such as higher bandwidth, bounded transmission delay, channel synchronization etc. have led to the need for efficient protocols and schemes used at all layers of the protocol stack from the network to the application layer. An attempt has ...

In this paper, we present the multimedia description scheme tools specified by the MPEG-7 standard for describing multimedia data such as images and video. In particular, we focus on the description tools that represent the structure and semantics of multimedia data to whose development we have actively contributed. We also describe some of our research prototype systems dealing with the extrac...

In this paper we present a model for the representation of multimedia applications based on the scenario concept. The scenario is described in terms of events and actions. The proposed model represents all the events that may occur in a multimedia application (originated from the system, the application or the user). As regards actions we propose a rich scheme for spatial an temporal compositio...

Multimedia production is generally considered to be an expensive task. This is true when dealing with complex graphics, animation, artistic effects, music and high quality video editing, but didactic applications do not require such advanced features. A conventional lesson can be effectively reproduced in a multimedia environment using a small set of multimedia features and a simple, regular st...

Annotation of multimedia resources supports a wide range of applications, ranging from associating metadata with multimedia resources or parts of these resources, to the collaborative use of multimedia resources through the act of distributed authoring and annotation of resources. Most annotation frameworks, however, are based on a closed approach, where the annotations data is limited to the a...
