Wavelet based multiresolution video representations generated by
multi-scale motion compensated temporal filtering (MCTF) and spatial
wavelet transform are disclosed. Since temporal filtering and spatial
filtering are separated in generating such representations, there are
many different ways to intertwine single-level MCTF and single-level
spatial filtering, resulting in many different video representation
schemes with spatially scalable motion vectors for the support of
different combination of spatial scalability and temporal scalability.
The problem of design of such a video representation scheme to full the
spatial/temporal scalability requirements is studied. Signaling of the
scheme to the decoder is also investigated. Since MCTF is performed
subband by subband, motion vectors are available for reconstructing video
sequences of any possible reduced spatial resolution, restricted by the
dyadic decomposition pattern and the maximal spatial decomposition level.
It is thus clear that the family of decomposition schemes provides
efficient and versatile multiresolution video representations for fully
scalable video coding.
