MAR docstring & interpolation method update #137

Closed dyang37 closed 1 year ago

dyang37 commented 1 year ago

This PR contains two components:

  1. Update the docstring of MAR weight as discussed yesterday: Screen Shot 2023-06-09 at 1 20 14 PM

  2. In multi resolution reconstruction, change the interpolation method from scipy.zoom() to skimage.rescale(), which yields a smoother interpolation with less high-frequency artifacts. As we observed last week, this results in faster convergence of the 3D shepp Logan problem (highest resolution recon: 18 iterations -> 15 iterations) without sacrificing image quality. This also reduces the software dependency. The mbircone source code does not require scipy anymore.

Works fine. I updated the script that automatically creates the conda environment, and I accepted the PR.
