The main intention of video coding in most video
applications is to reduce the amount of video signal for
storing and/or transmission purposes without affecting
its visual quality. On root of quality, disks capacity and
bandwidth the desired video performance can be achieve.
For portable digital video applications, highly-integrated
real-time video compression and decompression
solutions are required. In reality motion estimation
based encoders are the most usually used in video
compression techniques. Such encoders make use of

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.

An image defined in the real world is considered to be a function of two real variables say x,y.

Before going to processing an image, it is converted into a digital form. Digitization includes sampling of image and quantization of sampled values.

After converting the image into bit information, processing is performed.

This processing technique may be,
Image enhancement
Image reconstruction
Image compression

Image enhancement refers to accentuation, or sharpening, of image features such as boundaries.

Image restoration is con ....etc

Data Compression

Abstract :

It is very interesting that data can be compressed because it insinuates that information that we generally pass on to each other can be said in shorter information units (infos). Instead of saying yes a simple nod can do the same work, but by transmitting lesser data. In his 1948 paper, A Mathematical Theory of Communication, Shannon established that there is a fundamental limit to lossless data compression. This limit, called the entropy rate, is denoted by H. The exact value of H depends on the informatio ....etc
