Abstract EN
Video coding schemes for low bit-rate is of high importance and traditional coding schemes which use block transforms suffer from blocking artefacts.
Here we propose a video codec based on wavelet transform and hence performance of the coder is superior to other block transform based codecs.
The wavelet coefficients are coded using the computationally simpler no list SPIHT whose performance is similar to that of set partitioning in hierarchical trees.
Motion estimation is done using the recently proposed kite-cross-diamond search algorithm which is the fastest among the block matching algorithms.
The codec is ideally suited for sequences with smooth and gentle motion of the video conferencing kind.
Simulation results are provided to evaluate the performance of the code at various bit-rates.
The codec is scalable in terms of bandwidth requirement which means only one compressed bit stream is produced for different bit-rates.
The use of NLS makes the codec scalable since it has the embedded coding property.
However for resolution scalability different compressed files are required.
