Barbell-Lifting Based 3D Wavelet Coding
6.1 Introduction
We started the study of 3D wavelet-based video coding from motion threading for
exploiting long-term correlations across frames along motion trajectories [74, 86].
The work by Xu et al. [74] also proposes an efficient entropy coding, 3D embed-
ded subband coding with optimized truncation (ESCOT) for 3D wavelet coefficients.
However, the motion threading technique still has limitations on handling many-to-
one mapping and non-referred pixels. To solve these problems, Luo et al. further
develop the lifting-based motion threading technique [65, 76, 87].
Subsequently, additional effort has been invested in this area. Xiong et al. propose
multiple modes with different block sizes (similar ...
