Fast Directional Continuous Spherical Wavelet Transform Algorithms
Fast Directional Continuous Spherical Wavelet Transform Algorithms
We describe the construction of a spherical wavelet analysis through the inverse stereographic projection of the Euclidean planar wavelet framework, introduced originally by Antoine and Vandergheynst and developed further by Wiaux et al. Fast algorithms for performing the directional continuous wavelet analysis on the unit sphere are presented. The fast …
