Optimal Subband Rate Allocation for Spatial Scalability in 3D Wavelet Video Coding With Motion Aligned Temporal Filtering

Overview The shift-variant property of discrete wavelet transform leads to the intrinsic coupling across various spatial subbands during motion aligned temporal filtering. It brings a big challenge how to achieve a better trade-off between subband independency and motion alignment efficiency in the context of providing spatial scalability in 3D wavelet video coding. This paper first investigates the issue of subband coupling in-depth. From the investigations on analysis and synthesis filters, the paper verify the existence and causes of subband coupling phenomenon and illustrate the subband leakage due to motion shift.
