with Lower Buffering Requirements

Abstract-- Three-dimensional (3-D) video compression using
wavelets decomposition along the temporal axis dictates that a
number of video frames must be buffered to allow for the tem-
poral decomposition. Buffering of frames allows for the temporal
correlation to be made use of, and the larger the buffer the
more effective the decomposition. One problem inherent in such
a set up in interactive applications such as video conferencing,
is that buffering translates into a corresponding time delay. In
this paper, we show that 3-D coding of such image sequences can
be achieved in the true sense of temporal direction decomposition
but with much less buffering requirements. For a practical coder,
this can be achieved by introducing an approximation to the
way the transform coefficients are encoded. Applying wavelet
decomposition using some types of filters may introduce edge
errors, which become more prominent in short signal segments.
