126 6 Barbell-Lifting Based 3D Wavelet Coding
6.4.2 Subband Adaptive MCTF
In general, a frame to be coded highly correlates with previous frames. This correla-
tion can be exploited by generating a prediction through motion compensation. The
correlation strength is dependent on the distance between this frame and its refer-
ences and the accuracy of estimated motion vectors. Additionally, for a pair of the
current frame and its prediction, the correlation strength also varies in different spa-
tial frequency components. As shown in Figure 6.5, there is a frame to be coded
and its prediction. After packet wavelet transform, 16 subbands are
