Improvements to Radon-based noise removal

Improvements to Radon-based noise removal Mauricio D. Sacchi (Department of Physics University of Alberta) SUMMARY____________________________________________________________ I will discuss different strategies to improve the performance of Radon-based filtering with application to coherent noise removal. In particular I propose to combine multi-parameter Radon transforms (operators with more than one type of integration path) with filter banks. The latter significantly increases our ability to separate signal from coherent noise. I also examine new ways to gaining efficiency in the computation of time-variant Radon transforms. In particular time-variant multi-parameter Radon transforms can be quite demanding from the computational point of view when used for
