Abstract

Multimedia art catalogues present a number of recurring characteristics in both the type of data and the users involved, and in the type of operations required. Typical data include textual catalogue cards manageable through an information retrieval system (IRS), as well as textual captions, images, video and speech, strutured as a hypermedia network. Proposes a model for the design of these applications and discusses its effectiveness in improving the quality of the application. The model exploits a multi-level design approach to organize data and access structures of the IRS while the entity-relationship (E-R) approach, tailored to model hypermedia applications, is adopted to describe the structure of the documents and their links

Abstract

In this work, we face the problem of multimedia document indexing with reference to a specific application field, the radiological ward where automatic information managemenmt by content is an urgent need. Here, a multimedia document is composed of text and images. The keystone of the approach is the image indexing which is performed in an indirect way: the description of the image (made by an expert, in our case a physician) is further synthesised and formalised to be used by the computer. In this paper, we propose a concept-based indexing of the description of the images which is based on Farradane's work. The basic proposal has been extended to deal with specific requirements of the considered application and to be automatically performed. A first prototype of a multimedia information retrieval system has been implemented with the goal of validating the method in the specific application

Abstract

Proposes a new colour-based method for image databases. The method, integrating different approaches for describing colour information can be more satisfactory than standard techniques in fields such as textiles, ceramics, and paintings, when the user would like to retrieve from the database those images that actually resemble the query image selected in their colour distribution characteristics. Experimental trials on a database of complex antique textile images are reported and compared with human perceptual judgements, using an innocative procedure for estimating retrieval effectiveness
