Abstract


In this paper we present an efficient inter-scale motion vector prediction scheme for a wavelet based scalable video codec which uses inter-scale wavelet prediction. The scalable video codec considered in our work belongs to the class of 2D+t+2D schemes which applies 2-D spatial wavelet transform on the input data first, motion compensated temporal transform second and further spatial decomposition at the last stage. Although inter-scale wavelet coefficient prediction is proven to be very efficient in this coding scheme, inter-scale motion prediction has not yet been analyzed in this context. We propose a prediction scheme that enables exploitation of inter-scale motion redundancy and significantly enhances coding efficiency. PSNR increase of up to 1.45 dB and side information rate savings of up to 13% can be denoted, particularly for fast moving sequences.
