Abstract

We propose a hybrid low bit-rate subband video coding scheme utilizing context models, rate-constrained motion estimation and overlapped motion compensation. Emerging efficient context-based entropy coding techniques fit very well into wavelet/subband-based coding systems, making them very attractive candidates for the entropy coding part of a wavelet/subband-based video coding scheme. A multidimensional probability modeling technique along with context-based entropy coding are utilized to exploit redundancies in the subband structure, yielding better compression.
