size transform, secondary transform, and quantization technology. Entropy coding
technology, C2DVLC and CBAC, in AVS1 and AVS2 is detailed in Chap. 6 .
Chapter 7 mainly introduces the in-loop filter technology. Besides the improved
deblock filter, other two high-efficiency in-loop filters are discussed in detail.
With these above key technologies, coding performance is improved significantly.
Moreover, related works on these technologies are also discussed in detail.
Chapter 8 introduces some efficient video coding tools for scene videos, espe-
cially for surveillance video. The background redundancy features of surveillance
video are first analyzed. An overview for background picture model-based cod-
ing methods and typical background modes is provided. This chapter also gives a
detailed introduction for the background picture-based surveillance coding tech-
nology developed for emerging scene video applications in AVS2.
Chapter 9 introduces optimization technologies in video coding system from com-
plexity, performance, and compressed stream organization. For complexity, a
low-complexity intramode decision method is introduced, and for performance,
the flexible reference management, adaptive Lagrangian multiplier selection, and
perceptual-based coding methods are introduced and summarized. Finally, the file
format of the compressed stream is introduced.
Chapter 10 introduces a promising video coding system, intelligent video coding
system. It first introduces the basic modules and features for intelligent video
coding systems, and then provides an intelligent surveillance video coding system
based on AVS2. Some intelligent video coding technologies for video analysis are
introduced in this chapter.
Chapter 11 provides an overview of the quality assessment of image, video and
3D content. Both subjective database and state-of-the-art objective metrics are
summarized. The image and video quality assessment algorithms perform precise
and in-depth evaluation, comparison, design, and optimization of the image video
acquisition, processing, compression, storage, reproduction, delivery, and display
systems.
Chapter 12 introduces the hot research topics of video compression, including per-
ceptual video compression and Internet media-oriented compression. The coding
efficiency has been dramatically improved during the last 30 years. Driven by these
advanced coding techniques, we can still foresee the promising future in this area.
For the beginners in video coding, we suggest you should read the topic according
to the chapter order, and some basic knowledge in Chaps. 1 and 2 are necessary. For
video coding engineers who mainly want to learn about the major technologies in
AVS, you can directly read Chaps. 4 , 5 , 6 , and 7 . For some senior researchers, some
new techniques in video coding and interesting topics in Chaps. 10 , 11 , and 12 may
be more useful.
