In this paper we present a very general approach to indexing and retrieval of images in image database systems. We allow different ways of indexing and matching for objects in an image, and integrate them with our existing approach of the generalized extended pseudo-2D string and generalized combined 2D string representation of the image to formulate a more general framework for iconic indexing...

pacs is used as a way to store images and matches well with the workflow in the radiology department and can spread to other parts of hospital. integration with other pacs and other hospital systems like radiology information system (ris), hospital information system (his), and electronic patient records has been completely done, but there are still problems. pacs also provide good conditions f...

This draft deals with the Indexing and Retrieval (I & R) of graphic document images. We present first a general introduction on this topic and review then the main existing systems in the literature. Based on this review, we conclude on the unadaptability of existing systems to solve real-life indexing problems. We propose then a new system scheme based on three characteristics : a formalism al...

indexing is a largely used technique in retrieval systems. It has as goal to extract and to represent the meaning of a document so that it can be found by the user. We can cite two types of indexing: manual indexing, and automatic indexing. The automatic indexing requires to use character and words recognition engines which work only over the texts of contemporary documents. In this paper, we p...

Retrieval of multimedia has become a requirement for many contemporary information systems. These systems need to provide browsing, querying, navigation, and, sometimes, composition capabilities involving various forms of media. In this survey, we review techniques for text, image, audio and video retrieval. We first look at indexing and retrieval techniques for text, audio, image and video. We...

In this chapter, we explore ways to answer queries on large multi-dimensional data efficiently. Given a large dataset, a user often wants to access only a relatively small number of the records. Such a selection process is typically performed through an SQL query in a database management system (DBMS). In general, the most effective technique to accelerate the query answering process is indexin...

The Project German Indexing and Retrieval Test Data base (GIRT) provides a framework for the comparison of indexing and retrieval systems using German scientific information which is based on the social sciences. The aims and methods of the test environment are described. Some results of the pre-test, which was carried out with the retrieval systems Messenger and freeWAISsf, are shown and the c...

There has been no fundamental change in the dynamic indexing methods supporting database systems since the invention of the B-tree twenty-five years ago. And yet the whole classical approach to dynamic database indexing has long since become inappropriate and increasingly inadequate. We are moving rapidly from the conventional one-dimensional world of fixed-structure text and numbers to a multi...
