3-D wavelet-based scalable video coding provides a viable alternative to standard MC-DCT coding. However,many current 3-D wavelet coders experience severe boundary effects across group of picture (GOP) boundaries. This paper proposes a memory effcient transform technique via lifting that effectively computes wavelet transforms of a video sequence continuously on the ?y,thus eliminating the boundary effects due to limited length of individual GOPs. Coding results show that the proposed scheme completely eliminates the boundary effects and gives superb video playback quality.
