Multimedia data storage is a critical issue in large scale applications.

This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i

This paper deals with the problem of finding multimedia data that fulfill the requirements of user queries. We assume both the user query and the multimedia data are expressed by MPEG-7 standard. The MPEG-7 formalism lacks the semantics and reasoning support in many ways. For example, the search

The digital information revolution has brought about profound changes in our society and our lives. The many advantages of digital information have also generated new challenges and new opportunities for innovation. This thesis discusses the issues regarding multimedia data hiding and its

Is multimedia data mining just a new combination of buzz-words or is it a new interdisciplinary field which not only incorporates methods and techniques from the relevant disciplines, but is also capable to produce new methodologies and influence related interdisciplinary fields. Rather than

. Many existing models for temporal composition of multimedia data are based on the

for the degree of Doctor of Philosophy. The emerging popularity of multimedia data, as digital representation of text, image, video and countless other milieus, with prodigious volumes and wild diversity, exhibits the phenomenal impact of modern technologies in reforming the way information

This paper describes the Multimedia Data Exchange (MDE) Agent Pattern, which itself describes the decoupling of the communication mechanisms from the actual implementation of two multimedia components. The general model of Producer (Source), Filter, Consumer (Sink) that is used for the modeling

A very promising idea for fast searching in traditional and multimedia databases is to map objects into points in k-d space, using k feature-extraction functions, provided by a domain expert [Jag91]. Thus, we can subsequently use highly fine-tuned spatial access methods (SAMs), to answer several

tasks represent those new relationships that appear in the multimedia environment. In this paper, we discuss the effects of multimedia data on workflow specification and management in multimedia database systems. Two major types of the spatiotemporal dependencies among tasks, namely, progressive
