- W1986246612 abstract "Three-dimensional (t+2D) wavelet coding schemes have been demonstrated to be efficient techniques for videocompression applications. However, the separable wavelet transform used for removing the spatial redundancyallows a limited representation of the 2D texture because of spatial isotropy of the wavelet basis functions. Inthis case, anisotropic transforms, such as fully separable wavelet transforms (FSWT), can represent a solutionfor spatial decorrelation. FSWT inherits the separability, the computational simplicity and the filter bankcharacteristics of the standard 2D wavelet transform, but it improves the representation of directional textures,as the ones which can be found in temporal detail frames of t + 2D decompositions. The extension of bothclassical wavelet and wavelet-packet transforms to fully separable decompositions preserve at the same time thelow-complexity and best-bases selection algorithms of these ones. We apply these transforms in t + 2D videocoding schemes and compare them with classical decompositions." @default.
