Abstract
The wavelet filters of the conventional 3D multiresolution analysis po ssess homogeneous spatial and temporal frequency characteristics which Limits one's ability to match filter frequency characteristics to sig nal frequency behavior. Also, the conventional 3D multiresolution anal ysis employs an oct-tree decomposition structure which restricts the a nalysis of signal details to identical resolutions in space and time. This paper presents a 3D wavelet multiresolution analysis constructed from nonhomogeneous spatial and temporal filters, and an orthogonal su b-band coding scheme that decouples the spatial and temporal decomposi tion processes.
