Periodic Spline Wavelets and Wavelet Packets

2014
This chapter presents wavelets and wavelet packets in the spaces of periodic splines of arbitrary order, which, in essence, are the multiple generators for these spaces. The SHA technique provides explicit representation of the wavelets and wavelet packets and fast implementation of the transforms in one and several dimensions.

Wavelet Zoom

1999
Publisher Summary This chapter shows that the local signal regularity is characterized by the decay of the wavelet transform amplitude across scales. A wavelet transform can focus on localized signal structures with a zooming procedure that progressively reduces the scale parameter.

BLaC Wavelets and Non-Nested Wavelets

2002
Two multiresolution analyses (MRA) intended to be used in scientific visualization, and that are both based on a non-nested set of approximating spaces, are presented. The notion of approximated refinement is introduced to deal with non-nested spaces. The first MRA scheme, referred to as BLaC (Blending of Linear and Constant) wavelets is based on a one
