Distributed multimedia database system.

Abstract: A multiprocessor-based architecture is proposed for a heterogeneous multimedia database (HMD) system, in order to provide fast and transparent multimedia services. The design philosophy of this architecture is based on functional requirements imposed by the multimedia services. The model of the HMD architecture has four components: a network controller, multimedia servers, a communication network, and the user components. Each component is shown to be responsible for a subset of functions that are vital for providing the desired services.<>

Image database management in a multimedia system

Abstract: : A general concept for the representation of multimedia data by unformatted and formatted data is introduced. It leads to a basic-function approach to the design and development of multimedia database systems, which extends a relational database management system with new attribute types. In this paper, raster (or bitmap) images are used as an example. The structure of image values is defined, and a basic set of operations for access and manipulation is proposed. These operations can be integrated into a query language like SQL. To facilitate a contents-oriented search on multimedia data in general and on images in particular, text descriptions are introduced into the database that allow users to indicate the contents of an image. The well established techniques of information retrieval can be applied to search for these descriptions. The proposed system allows us to model images that are assigned to objects as well as stand-alone images. The paper finally sketches a prototype implementation on top of an existing relational database management system (Ingres). Keywords: Multimedia databases, Image databases, Theses. (mjm)

Knowledge-based multi-media database management system and its application to map information systems

Abstract: A structure of a multimedia database management system that enables inferential retrieval and automatic construction is proposed It consists of three parts, namely, a knowledge base at the top, a relational manager in the middle, and a media-oriented manager at the bottom An automatic recognition and data input method for map figure data and an automatic database construction method and renewal capability are introduced The effectiveness of these methods has been confirmed by applying them to a prototype map-based system for utility management >

A program interface prototype for a multimedia database incorporating images.

Abstract: This thesis represents one aspect of an exploration of the integration of unformatted data types, such as image, sound and signal, with more conventional formatted types in a single database. The focus of this thesis is the implementation of a prototype of a database employing a relational model that incorporates both formatted and unformatted data types. Initial research was limited to integration of image data. The prototype provides storage and retrieval capabilities, as well as a modest queryhandling capability.

Managing sound in a relational multimedia database system.

Abstract: : Sound, in all of its varied forms, is an important and widely used medium for the transmission of information. The widespread use of computers has greatly increased the breadth and depth of our information processing abilities. Yet the limited sensory functionality of computers has traditionally dictated a predominantly alphanumeric or 'textual' communications interface standard. This thesis concentrates on the effective manipulation (i.e., capture, storage and retrieval) of sound data in a relational database system. It introduces the concept of an abstract data type of type SOUND which permits a level of sophistication in data manipulations that is beyond the capabilities of current systems. Such sophistication is accomplished through the use of a set of data manipulation operations which effectively hide the representation of the SOUND data structure from the user. As a result, the current familiarity of the user's view of the database remains unchanged when extended to the multimedia information processing environment. Keywords: Digitizing, Encoding, Theses.

Multimedia Database at National Museum of Ethnology

Abstract: 国立民族学博物館は民族学研究の情報センターとして, 図書, 論文, 標本資料, 映像音響資料, HRAF (人間関係地域ファイル) などを収集し, 研究に活用できるようコンピュータ化を行っている。現在約130万件の民博独自なデータベースを構築している。これは単に文字表記による書誌的事項のみならず, できるだけ現物に近い情報を提供できるよう, マルチメディアのデータベースを構築している。標本資料の平面, 正面, 側面, 鳥瞰からの映像の蓄積検索システムや, スライドイメージの検索, 本のページイメージの検索など画像データベースの実験を試みている。
