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

8. SCOPE OF MPEG-7

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.

MPEG-7

13. MPEG-7 APPLICATION
 Digital library:-image/video catalogue, musical
dictionary
 Multimedia directory services:- e.g-yellow pages.
 Broadcast media selection:- radio channel, TV
channel
 Multimedia editing:-media authoring

14. MPEG-7 APPLICATION
 Security services:-traffic control
 E-business:- searching process of products
 Cultural services:- museums, art-galleries
 Educational appliction
 Biomedical application
