Hey Luis, >From the deafening silence to your question, I'd say no. I had a quick look around CPAN and I see nothing for Radon in PDL or Perl in general.
Then I had a look at what a Radon Transform <https://en.wikipedia.org/wiki/Radon_transform> actually is and it is **well cool**! We were talking last week about the episode of House with the bullet fragments and the MRI machine and started asking, how _do_ you get a 3D image from a bunch of attenuations? As it's not far off the Fourier transform, I'd say it's possible and maybe PDL::Transform's map <https://metacpan.org/pod/PDL::Transform#map1> function with it's { map => 'fft' } option is a place to start hacking. I'll have some free time in a couple of months if you want a willing novice-to-PDL collaborator. It sounds like something that Perl should have in it's toolbox if we want our language to be serious about Scientific Perl. I think I've got a "tuit" around here somewhere. :) Saludos, Boyd On Thu, Mar 5, 2020 at 4:37 AM Luis Mochan <[email protected]> wrote: > Hi, > > Is there an implementation of the Radon transform and its inverse in > PDL?
