Speed benchmarks

All methods are benchmarked using their default parameters, with the following exceptions:

  • basex(var) and daun(var) mean “variable regularization”, that is changing the regularization parameter for each transformed image.
  • direct_C and direct_Python correspond to the “direct” method using its C (Cython) and Python backends respectively.
  • linbasex and rbasex show whole-image (n × n) transforms, while all other methods show half-image (n rows, (n + 1)/2 columns) transforms.
  • rbasex(None) means no output-image creation (only the transformed radial distributions).
