Abstract
- In this chapter, we examine the ideas behind the MPEG standards, starting with MPEG-1, -2, and then MPEG-4, and 7. In MPEG-1 and -2, bidirectional search for motion vectors is introduced. Interlaced video and high-definition TV (HDTV) are supported in MPEG-2. Moreover, it supports various scalable codings such as SNR, spatial, temporal, and their combination. MPEG-4 and -7 studied the issue of video coding based on video objects. Although the visual object-based video representation and compression approach developed in MPEG-4 and 7 have not been commonly used in current popular standards such as H.264 and H.265, it has great potential to be adopted in the future when the necessary Computer Vision technology for automatic object detection becomes more readily available.
