In recent years, the paradigm of video coding has shifted from that
of a frame-based approach to a content-based approach, particularly
with the finalization of the ISO multimedia coding standard,
MPEG-4. MPEG-4 is the emerging standard for the coding of
multimedia content. It defines a syntax for a set of content-based
functionalities, namely, content-based interactivity, compression
and universal access. However, it does not specify how the video
content is to be generated. To generate the video content, video
has to be segmented into video objects and tracked as they
transverse across the video frames. This book addresses the
difficult problem of video segmentation, and the extraction and
tracking of video object planes as defined in MPEG-4. It then
focuses on the specific issue of face segmentation and coding as
applied to videoconferencing in order to improve the quality of
videoconferencing images especially in the facial region.
Modal-based coding is a content-based coding technique used to code
synthetic objects that have become an important part of video
content. It results in extremely low bit rates because only the
parameters needed to represent the modal are transmitted.
Model-based coding is included to provide background information
for the synthetic object coding in MPEG-4. Lastly, MPEG-4, the
first coding standard for multimedia content is described in
detail. The topics covered include the coding of audio objects, the
coding of natural and synthetic video objects, and error
resilience.
"Advanced Video Coding" is one of the first books on content-based
coding and MPEG-4 coding standard. It serves as an excellent
information source and reference for both researchers and
practicing engineers.
