Digitization includes sampling of image and quantization of sampled values. After converting the image intobinary, processing is performed which maybe:
-Image enhancement
- Image reconstruction
- Image compression
Image compression deals with minimizing the no of bits required to represent an image.
An image in the real world is considered to be a function of two real variables, for example, F(x,y) with F as the amplitude (e.g. brightness) of the image at the position (x,y). An image contains regions-of-interests to which specific ima ....etc

Abstract
We present an adaptive lossless video compression algorithm based on predictive coding. The proposed algorithm exploits temporal, spatial, and spectral redundancies in a backward adaptive fashion with extremely low side information. The computational complexity is further reduced by using a caching strategy. We also study the relationship between the operational domain for the coder (wavelet or spatial) and the amount of temporal and spatial redundancy in the sequence being encoded. Experimental results show that the proposed s ....etc

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
inter- ....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

H.265/HEVC video encoding consumes only half the bandwidth of H.264 encoding for the same video quality, which makes it essential for 4K2K video. Vanguard Video has developed an H.265/HEVC video codec that complies with the latest HEVC draft spec. Perhaps the most interesting aspect to this codec is that Vanguard has implemented a real-time version of it for 4Kp30 video in software (C and hand-tweaked, to-the-max assembly language for selected algorithms), which encourages comparison. The software version of the codec runs in real time on fou ....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.
