Motion Threading for 3D Wavelet Coding
5.1 Introduction
Wavelet transform [57] provides a multi-scale representation of image and video
signals in the space-frequency domain. Aside from energy compaction and decor-
relation properties that facilitate efficient compression of natural images, a major
advantage of wavelet representation is its inherent scalability. It endows compressed
video and image streams with flexibility and scalability in adapting to heterogeneous
and dynamic networks, diverse client devices, and the like. Furthermore, recent pro-
gresses in literature have shown that 3D wavelet-based video coding schemes are
able to compete in performance with the conventional hybrid standard approaches
(e.g., H.264/AVC [13]).
