Spherical Needlets for CMB Data Analysis
D. Marinucci, D. Pietrobon, A. Balbi +6
We discuss Spherical Needlets and their properties. Needlets are a form of spherical wavelets which do not rely on any kind of tangent plane approximation and enjoy good localizati…
Subsampling needlet coefficients on the sphere
P. Baldi, G. Kerkyacharian, D. Marinucci +1
In a recent paper, we analyzed the properties of a new kind of spherical wavelets (called needlets) for statistical inference procedures on spherical random fields; the investigati…
Needlet algorithms for estimation in inverse problems
Gérard Kerkyacharian, Pencho Petrushev, Dominique Picard +1
We provide a new algorithm for the treatment of inverse problems which combines the traditional SVD inversion with an appropriate thresholding technique in a well chosen new basis.…
