      Inversion of noisy Radon transform by SVD based needlets 

      Kerkyacharian, G.; Kyriazis, George C.; Le Pennec, E.; Petrushev, P.; Picard, D. (2010)
      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 transform SVD basis. Upper bounds of the ...
