Whereas much of the previous work on data mining has focused on mining data in relational databases, in this paper we discuss mining objects. Object models are very popular for representing multimedia data and, therefore, we need to mine object databases to extract useful information from the large quantities of multimedia data. We first describe the motivation for multimedia data mining with e...

In this paper we highlight major technical requirements for designing and developing future distributed multimedia information system using Internet technology. The key requirements of this system are to allow users to access and search and to communicate multimedia documents consisting of text, audio, video, and image. We emphasize the role of object-oriented technology for information managem...

In the present world when whole web is now coming on from text data to multimedia data, one of the major security concerns is the protection of this multimedia data. Image, which covers the highest percentage of the multimedia data, its protection is very important. This can be achieved by Image encryption. There are so many different techniques should be used to protect confidential image data...

In this paper, a security model is proposed which imposes the concept of secrecy over privacy for text messages. In the recent years, we have plenty of security tools which are developed to protect the transmission of multimedia objects. But approaches for the security of text messages are comparatively less. The model proposed by us combines cryptography, steganography (taken as security layer...

Multimedia is referred to ideally as the use of computers to present text, graphics, video, animation, and sound in an integrated way. But, in reality, “integration” is read as “synchronization” among those media. The term multimedia reminds us of the existence of multiple media. In this paper, we present a notion of UniversalMedia. It is not just text, or graphics, or video, or animation, or s...

Multimedia contents are more and more present in our life and their presentation usually rests on a text-based description that defines rules and properties of such contents and is produced by markup description languages (e.g., XML, MPEG7-DDL and SMIL). Although effective, the criticism to such approach regards the length of the produced description, which is considered too verbose. Since this...

The Session Initiation Protocol (SIP) is a text-based protocol for initiating and managing communication sessions. The protocol can be compressed by using Signaling Compression (SigComp). Similarly, the Session Description Protocol (SDP) is a text-based protocol intended for describing multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedi...

We used a flexible XML retrieval system for evaluating structured document retrieval and multimedia retrieval tasks in the context of the INEX 2006 benchmarks. We investigated the differences between article and element retrieval for Wikipedia data as well as the influence of an elements context on its ranking. We found that article retrieval performed well on many tasks and that pinpointing th...

Ahtract We describe an experimental multimedia information system for an office environment which is being developed in the University of Toronto. Multimedia messages are composed of text, image, voice and attribute information. We discuss issues related to internal representation, presentation and cornmunication with the outside world, content addressahility in the various data types, user int...

Most of the research in multimedia retrieval applications has focused on retrieval by content or retrieval by example. Since the classical review by Smeulders, Worring, Santini, Gupta, and Jain (2000) a new interest has grown immensely in the multimedia information retrieval community: retrieval by semantics. This exciting new research area arises as a combination of multimedia understanding, i...
