MPEG-7



Introduction
Accessing audio and video used to be a simple matter - simple because of the simplicity of the access mechanisms and because of the poverty of the sources. An incommensurable amount of audiovisual information is becoming available in digital form, in digital archives, on the World Wide Web, in broadcast data streams and in personal and professional databases, and this amount is only growing. The value of information often depends on how ....etc

MPEG-2 VIDEO COMPRESSION TECHNIQUE

Abstract:
MPEG-2 is an extension of the MPEG-1 nternational standard for digital compression of audio and video signals.MPEG-1 was designed to code progressively scanned video at bit rates up to about 1.5 Mbit/s for applications such as CD-I (compact disc interactive). MPEG-2 is directed at broadcast formats at higher data rates; it provides extra algorithmic tools' for efficiently coding interlaced video supports a wide range of bit rates and provides ....etc

MPEG-4 is an ISO/IEC standard being developed by MPEG (Moving Picture Experts Group), the committee which also developed the Emmy Award winning standards known as MPEG-1 and MPEG-2. These standards made interactive video on CD-ROM and Digital Television possible. MPEG-4 will be the result of another international effort involving hundreds of researchers and engineers from all over the world. MPEG-4, whose formal ISO/IEC designation will be ISO/IEC 14496, is to be released in November 1998 and will be an International Standard in January 1999.

As more and more audiovisual information becomes available from many sources around the world, many people would like to use this information for various purposes. This challenging situation led to the need for a solution that quickly and efficiently searches for and/or filters various types of multimedia material that's interesting to the user.
For example, finding information by rich-spoken queries, hand-drawn images, and humming improves the user-friendliness of computer systems and finally addresses what most people have been ....etc

MPEG is the famous four-letter word which stands for the Moving Pictures Experts Groups.
To the real word, MPEG is a generic means of compactly representing digital video and audio signals for consumer distributionThe essence of MPEG is its syntax: the little tokens that make up the bitstream. MPEG's semantics then tell you (if you happen to be a decoder, that is) how to inverse represent the compact tokens back into something resembling the original stream of samples.

These semantics are merely a collection of rules (which ....etc

For real time facial animation on the web, following are the important requirements:
1). Easy installation: like in most of the application, the virtual presenter is not the most important attraction of the proposed services. For this, we would not use any plug-in and the complete applet development (Shout3D rendering + deformation engine) is pure java.

2). Visual quality: in case of the virtual talking heads on the web looks and realism are of utmost importance. In the case of the virtual cartoon-like character, we can be freer to use arti ....etc

MPEG-VIDEO COMPRESSION TECHNIQUE
ABSTRACT
MPEG is a famous four letter word which stands for the moving pictures Experts Group.
To the real world, MPEG is a generic means of compactly representing digital video and audio signals for consumer distribution. The basic idea is to transform a steam of discrete samples into a bit stream of tokens which takes less space, but is just as filling to the eye or near). This transformation or better representing exploits perceptual and even some actual statistic redu ....etc
