Shift-invariant spaces from rotation-covariant functions.
Appl. Comput. Harmon. Anal. 25, 240-265 (2008)
We consider shift-invariant multiresolution spaces generated by rotation-covariant functions {rho} in R2. To construct corresponding scaling and wavelet functions, {rho} has to be localized with an appropriate multiplier, such that the localized version is an element of L2(R2).We consider several classes of multipliers and show a new method to improve regularity and decay properties of the corresponding wavelets. The wavelets are complex-valued functions, which are approximately rotation-covariant and therefore behave as Wirtinger differential operators. Moreover, our class of multipliers gives a novel approach for the construction of polyharmonic B-splines with better polynomial reconstruction properties.
