Compressed sensing imaging techniques for radio interferometry
Y. Wiaux, L. Jacques, G. Puy +2
Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actual…
Fast directional correlation on the sphere with steerable filters
Y. Wiaux, L. Jacques, P. Vielva +1
A fast algorithm is developed for the directional correlation of scalar band-limited signals and band-limited steerable filters on the sphere. The asymptotic complexity associated…
Fast spin +-2 spherical harmonics transforms and application in cosmology
Y. Wiaux, L. Jacques, P. Vandergheynst
A fast and exact algorithm is developed for the spin +-2 spherical harmonics transforms on equi-angular pixelizations on the sphere. It is based on the Driscoll and Healy fast scal…
Correspondence principle between spherical and Euclidean wavelets
Y. Wiaux, L. Jacques, P. Vandergheynst
Wavelets on the sphere are reintroduced and further developed independently of the original group theoretic formalism, in an equivalent, but more straightforward approach. These de…
