Summary on Grant Application Form
(1) To research methods for enhancing an open architecture multimedia information system to enable it to support techniques for handling image and video sequences which use image content directly(2) To innovate some specific techniques for the above and integrate them into the open architecture MMIS(3) To assess the benefits and productivity gains of these techniques both to multimedia information systems authors and end usersProgress:Manual link authoring in hypermedia systems is a time consuming process. Microcosm is an open hypermedia system that attempts to solve this problem by providing two powerful alternatives to manual link creation: generic links, which are defined on an object as a source anchor and can be followed any time that object appears in a document, and computed links, which compute destinations from a pre-indexed set of documents by carrying out a similarity match against the index based on the source anchor. In the original system, generic links and computed links could only be defined for text source anchors. Unlike text, where the only comparison used to match text anchors or document indexes is a string match, richer media such as images required many different matching algorithms.The focus for the first year of this project has been the extension of the Microcosm architecture to allow generic and computed links to be used with non-textual documents. The extension, called MAVIS (Microcosm architecture for video, image and sound) takes the form of a framework containing a collection of signature modules. Each module is responsible for supporting everything needed to produce and maintain indexed representations ( signature ) of the content. Modules have been implemented to handle signatures based on colour distribution, basic shape and texture so that content based retrieval and navigation based on these image features is now possible. Prototype modules have also been developed for creating signatures for sound and video. We are currently implementing a non-rectangular source anchor selection capability, faster indexing strategies and the integration of third party image handling software to provide more flexible facilities for end users. The MAVIS system is being assessed through the development of two applications - a database of archaeological artifacts and a furniture catalogue for a major retail chain. This work has been presented at two conferences, and a journal article is in preparation.
