In this paper, we present a fully scalable wavelet-based video coding
architecture called STP-Tool, in which motion-compensated temporal-filtered
subbands of spatially scaled versions of a video sequence can be
used as a base layer for inter-scale predictions. These predictions
take place in a pyramidal closed-loop structure between homologous
resolution data, i.e., without the need of spatial interpolation.
The presented implementation of the STP-Tool architecture is based
on the reference software of the Wavelet Video Coding MPEG Ad-Hoc
Group. The STP-Tool architecture makes it possible to compensate
for some of the typical drawbacks of current wavelet-based scalable
video coding architectures and shows interesting objective and visual
results even when compared with other wavelet-based or MPEG-4 AVC/H.264-based
scalable video coding systems. |
