@evgueni-ovtchinnikov, this all works fine. thanks!
Could you rename set_alpha_ramp
to set_alpha_cosine_window
? Add some doc for the class like:
This is an implementation of the 2D FBP algorithm.
Oblique angles in data will be ignored. The exception is the span=1 case, where the ring differences +1 and -1 are first combined to give indirect sinograms.
By default, the algorithm uses the ramp filter. An apodizing filter can be added by using set_alpha_cosine_window and/or set_frequency_cut_off. The apodizing filter in frequency space has the form
(alpha + (1 - alpha) * cos(pi * f / fc))
Add doc to set_alpha_cosine_window
Set alpha in the apodizing filter.
See the class documentation for the filter. alpha should be between 0.5 and 1. alpha=0.5 corresponds to the Hann filter, while 0.54 corresponds to the Hamming filter.
and for set_frequency_cut_off
Set the cut-off frequency for the apodizing filter.
See the class documentation for the filter. fc should be between 0 and 0.5.
Could you then expose this to matlab as well?
