5. INTRODUCTION OF MPEG-7
MPEG-7 is actually a standard developed by
“moving picture experts group” in 2001.
MPEG-7 is a multimedia content description
standard.
It was standardized in ISO/IEC/15938(multimedia
content description interface)
6. MPEG-7 is formally called Multimedia content
description interface.
MPEG-7 is the standard that describes multimedia
content so users can search, browse & retrieve that
content more efficiently & effectively.
7. PARTS OF THE MPEG-7 STANDARD
ISO/IEC 15938-1 System
ISO/IEC 15938-2 Description definition
language
ISO/IEC 15938-3 Visual
ISO/IEC 15938-4 Audio
ISO/IEC 15938-5 Multimedia description
schemes
ISO/IEC 15938-6 Reference software
9. SCOPE OF MPEG-7
The description generation (feature extraction,
indexing process, annotation & authoring tools etc) &
consumption (search engine, filtering tool, retrieval
process, browsing device etc) are non normative
parts of MPEG-7.
The goal is to define the minimum that enables
interoperability.
10. MPEG-7 TOOLS
Descriptor (D):-representations of features, that
define the syntax & the semantics of each feature
representation (low level)
Description schemes (DS):-that specify the
structure & semantics of the relationship between
their components, which may be both DS &DSs.
11. MPEG-7 TOOLS
Description definition language(DDL):-based on
XML schema to allow the creation of new DSs & DS
& to allow the extension & modification of existing
DSs.
System tools:- these tools deal with binarization,
synchronization transport & storage of descriptors. it
also deals with intellectual property protection.
