ABSTRACT
Wavelet transform [57] provides a multi-scale representation of image and video signals in the space-frequency domain. Aside from energy compaction and decorrelation 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 progresses 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]).
