| Abstract: | In this paper,three dimensional wavelet transform based on bidirectional motion compensation was presented.Compared with past three dimensional wavelet transform algorithm,the method combines two temporal scalable schemes: layer coding and 3D wavelet video coding.Bidirectional motion estimation/compensation is applied to 3D wavelet video coding to achieve high quality scalable video coding. |
