Inversion of noisy Radon transform by SVD based needlet
Gérard Kerkyacharian, George Kyriazis, Erwan Le Pennec +2
A linear method for inverting noisy observations of the Radon transform is developed based on decomposition systems (needlets) with rapidly decaying elements induced by the Radon t…

Adaptive density estimation for directional data using needlets
P. Baldi, G. Kerkyacharian, D. Marinucci +1
This paper is concerned with density estimation of directional data on the sphere. We introduce a procedure based on thresholding on a new type of spherical wavelets called {\it ne…
