Masked Synthetic Ptychographic Iterative Engine (msPIE)

There are two packages. One for msPIE reconstruction and the other for registering reconstructed images.

To test the msPIE, download the testdata from DOI 10.5281/zenodo.11114459. Run msPIE_Sequence and results will be saved at msPIE_Results under the same directory. Reconstructing all four frames at given setting will take ~10 hours.

For improved SNR, the registration package provides a jupyter notebook for rigid registration. Change the image reading directory 'dir' to your directory where 'msPIE_Results' is at and run through the notebook. It will perform rigid registration for the 4 reconstructed ptycho images and save the averaged image.
