Avoiding retrieval contention for composite multimedia objects

This paper presents a novel multimedia retrieval technique, called Progressive Query (PQ). PQ is designed to bring an effective solution especially when querying large-scale multimedia databases. In addition, PQ produces intermediate query retrieval results during the execution of the query. The series of intermediate query results will finally converge to the fullscale search retrieval in a faster way and with no minimum system requirements. Experimental progressive query retrieval results show that intermediate retrieval results may be satisfactory and further query processing time may be avoided.

In multi-user multimedia information systems (e.g., movie-on-demand, digital-editing), scheduling the retrievals of continuous media objects becomes a challenging task. This is because of both intra and inter object time dependencies. Intra-object time dependency refers to the real-time display requirement of a continuous media object. Inter-object time dependency is the temporal relationships de ned among multiple continuous media objects. In order to compose tailored multimedia presentations, a user might de ne complex time dependencies among multiple continuous media objects having various length and display bandwidth requirement. Scheduling the retrieval tasks corresponding to the components of such a presentation in order to respect both inter and intra task time dependencies is the focus of this study.

Due to the fact that the speeds of secondary storage devices have not improved relative to other computing technologies, a lot of efforts have been devoted to intelligent and efficient ways of storing data of storing data to maximixe the bandwidth of a computing system. Many of those techniques have proven useful; however, with the advent of multimedia and its enormous real-time and size requirements, the problems of data allocation and retrieval have become even more crucial. In [1][2], we describe some designs of efficient multimedia object storage strategies that strive to allocate multimedia objects with the objective of satisfying their real-time retrieval requirements. We utilize some fragmentation strategies, a cost function, and bipartite graph model to allocate multimedia data efficiently. In the development of the storage allocation strategies, some assumptions were made about the functionalities and capabilities of the controlling Multimedia Object Manager. Here, we describe...

Storage and Retrieval for Image and Video Databases VI, 1997

It is becoming increasingly important for multimedia databases to provide capabilities for content-based retrieval of composite objects. Composite objects consist of several simple objects which h a ve feature, spatial, temporal, semantic attributes, and spatial and temporal relationships between them. A content-based composite object query is satis ed by e v aluating a program of content-based rules i.e., color, texture, spatial and temporal rules i.e., east, west, fuzzy conjunctions i.e., appears similar AND is spatially near and database lookups i.e., semantics.

The Management of user interactions in distributed multimedia presentations requires addressing new challenging issues. In this paper, we revue the semantic of VCR-like interactions. We argue that using VCR commands in the same way as it is done with video data (accelerating the presentation) is not suitable. Furthermore, those interactions are semantically linked to the content of the presentation; the final objective of users is to quickly browse and access a certain content. Firstly, we define a novel adequate semantic of VCR-like interactions for multimedia presentations. It considers human understanding of accelerated multimedia presentation, as the most important criterion to be taken into account. Secondly, we propose an integrated preloading and replacement strategy, named Content-based Prefetching Strategy (CPS) as a suitable buffer management strategy for those VCR-like functionalities. Finally, we show by multiple series of experimentations that CPS observes minimum response time for VCR-like interactions.

Several years have passed since the research topic of content based multimedia retrieval emerged. We have witnessed the burgeoning research activities into a plenitude of new indexing, retrieval, and filtering tools for images, video, audio, music, graphics, and their combinations with text-based information. Exciting research opportunities arise when integrating knowledge from multiple disciplines, such as media content processing, database, information retrieval, and machine user interface. In the commercial domain, we have also witnessed several impressive efforts moving technologies into practical arenas.

Architectural Issues of Web-Enabled Electronic Business, 2000

The objective of this chapter is to introduce the reader to a general architectural framework for a broad array of retrievals of multimedia data required by various applications. This framework contains more than the traditional client/server architecture and even more than the existing three-tier architectures. This chapter introduces the reader to many critical issues involved in multimedia retrieval over the Internet. A new architectural framework is proposed to cover a variety of multimedia applications over the Internet and the World Wide Web. This framework has the three main objectives of (1) proposing a layered architecture to facilitated design and separate different issues, (2) covering a large number of multimedia applications, and finally, (3) making use of existing and well-established technology, such as Mobile Agents, SQL databases, and cache managements schemes. The proposed architectural framework separates issues involved in multimedia retrieval into five layers, namely: keyword searching and data servers, proxy servers, domain and department archives, mobile user agents, and the users. Through these five layers, various customized solutions to a large array of problems will be proposed and applied. The chapter offers, but is not limited to, solutions for different problems that arise in retrieval of multimedia data. A list of important open problems is identified at the end of the chapter.
