S2LET: A code to perform fast wavelet analysis on the sphere

1 code implementation7 Nov 2012 B. Leistedt, J. D. McEwen, P. Vandergheynst, Y. Wiaux

Wavelets are constructed through a tiling of the harmonic line and can be used to probe spatially localised, scale-depended features of signals on the sphere.
