Abstract

We present a spatially adaptive wavelet video coding technique with an update-first lifting structure. A common problem in many adaptive-transform frameworks is the introduction of a large overhead to address side information. We demonstrate that our structure does not need to transmit any side information to synchronize the encoder and decoder. We incorporate this technique in a motion compensated wavelet video codec. The experimental results confirm the performance improvement.
