Abstract

We present a highly scalable wavelet-based video coder, featuring a scan-based motion-compensated temporal wavelet transform (WT) with lifting schemes which have been specially designed for video. Output bitstream is compatible with JPEG2000, as it is used to compress temporal subbands (SBs). Rate allocation among SBs is done by means of an optimal algorithm, which requires SBs rate-distortion (RD) curves. We propose a model-based approach allowing us to compute these curves with a considerable reduction in complexity. The use of temporal WT and JPEG2000 guarantees high scalability.
