Definition:MPEG-4 multimedia compression standard was developed to provide technological foundations to deal with multimedia content in object-based, interactive, and non-linear way.
Consequently, MPEG-4 video (Part 2 of the MPEG-4 standards series) had to meet the need with shape coding for arbitrary shaped video representation. Since MPEG-4 is a generic coder, the standard includes many algorithms/tools that can be used for a variety of applications under different operating conditions. Compared with the MPEG-2 standard, MPEG-4 covers novel profiles and levels with shape coding and low-bit rate tools additionally. As a result, wireless phone standards such as 3GPP include MPEG-4 video as a video subsystem compression standard. This section discusses about MPEG-4 video natural coding tools focusing on shape coding and texture coding.
MPEG-4 Shape Coding
There are two types of shape data in MPEG-4: grey scale and binary shape information. Context-based Arithmetic Encoding (CAE)...
