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]).
