Tj. Burns et al., A WAVELET MULTIRESOLUTION ANALYSIS FOR SPATIOTEMPORAL SIGNALS, IEEE transactions on aerospace and electronic systems, 32(2), 1996, pp. 628-649
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.
