, and the use of image texture for content representation. Built upon these technologies are techniques for managing large repositories of data. A texture thesaurus assists in creating a semantic classification of image regions. An object-based representation is proposed to facilitate data storage, retrieval

. The classication process is made more ecient when classes are organized into a hierarchy. A hierarchy of classes is also the basis of object-based representation systems (obrs) where knowledge is represented within classes and classication is used for reasoning, as in description logics [ Nebel,1990 ] [ Donini et

In this paper, we deal with the similarities between object database models and concept languages, establishing a correspondence between the two environments. Object Database Models deal with two kinds of data: individual objects, which have an identity, and values, which can be basic values or can

representations. keywords Object-Based Representation, Similarity Measure, Classification, Categorization. 1. Motivations The aims of Object Based Representation Systems (OBRS) are twofold: on the one hand they allow to store and to organise a domain knowledge; on the other hand, they allow to answer some user

In this position paper, we present a proposal for a layered architecture for a hybrid object-based rep-resentation system, relying on two kinds of repre-sentation formalisms, namely description logics and

for dealing with the representation issues. Featurebased, grid-based and direct methods are integrated into the framework of the hierarchical object based representation. The sampling and correlation based range image matching algorithm is developed to tackle the problem arising from uncertain, sparse

We introduce an object-based multimedia stream representation model using XML and present a system that supports conformance to device capabilities and user control in multimedia stream transformation and presentation.
