Componentes para manipulação de objetos multimídia utilizando o padrão MPEG-7

Abstract

This work presents a layer for the manipulation of media based on the multimedia content description interface, MPEG-7. This layer realizes some parts of the MPEG-7 MDS (Multimedia Description Schemes), and being built by components, makes a base for the implementation of any application that has media manipulation requisites that range from the simplest ones to a database multimedia system. In this last case, it can be a system that have many operations being executed in a database, like multimedia data mining and indexing by low level features, all supported by MPEG-7. This layer was built to unify the necessities on manipulating media of many applications, integrating them and acting as a mediator. It provides interfaces so that the insertion of media together with their semantic annotation is possible, along with queries based on these semantic metadata derived from these annotations. A simplified model for the semantic annotation and queries for the ease of use of these interfaces was proposed, being the annotations and queries made in a similar manner. Finally, this layer allows the exporting of the query metadata on the format used by MPEG-7 for interchange between systems.
