Visual Information Retrieval for the WWW
In this paper we present the conception and the evaluation of a visual information retrieval system for the Web. Our work has been motivated by the lack of good user interfaces assisting the user in searching the Web. The selected visualisations and the reasons why they have been chosen are explained in detail. An evaluation of these visualisations as an add-on to the traditional result list is...
متن کاملRobust Color Image Retrieval for the WWW
The rapid growth of image archives increases the need for efficient and fast tools that can retrieve and search through large amount of visual data. In this paper an efficient method of extracting the image color content is proposed, which can serve as an image digital signature, allowing to efficiently index and retrieve large multimedia Internet based databases. The proposed method was applie...
متن کاملA WWW-based Melody Retrieval System
あらまし 本論文では,WWW上で動作する,歌声の旋律からその曲のタイトルを検索するシステムについ て述べる.歌声による検索では,入力の旋律情報(音高・音長)が正確とは限らないため,しきい値によってそ れらを粗い旋律情報に変換したものを検索キーとし,データベースの曲とのマッチングを行う.しかし,このた めの適切なしきい値の設定は難しく,特に音長情報においては,有効な検索キーを得ることが困難であった.ま た,粗い旋律情報では正答の絞込みも難しい.そこで,本研究では( 1)有効な検索キーを得るための最適なし きい値を設定する手法, ( 2)データベースの曲から正答の曲の候補を精度良く絞り込むためのマッチング手法の 二つを提案することで,従来手法よりも正答率の高い検索を実現し,WWW上で複数の利用者が活用できるシ ステムを構築できた. キーワ ドー 音楽データベース,メロディ検索,WWWアプ...
متن کاملWWW Multicast Delivery with Classes of Service
At busy WWW servers the inter-reference times of some documents may be low enough for duplicate requests to be accumulated and held over some small time interval before servicing the duplicate requests via a single multicast at the end of the time interval. The use of multicast in this way will reduce the bandwidth consumption on the server output link. We present a scheme that extends these pr...
متن کاملMobile Agents for Content-Based WWW Distributed Image Retrieval
At present, the de-facto standard for providing contents in the Internet is the World Wide Web. A technology, which is now emerging on the Web, is Content-Based Image Retrieval (CBIR). CBIR applies methods and algorithms from computer science to analyse and index images based on their visual content. Mobile agents push the flexibility of distributed systems to their limits since not only comput...
