Notes:

18000467: Sparse Modeling (L1+TV regularization) - The raw reconstructed image from uvfits files solved with L1+TV regularization and MFISTA algorithm from the complex visibilities.
49319591: Closure Only Imaging
85727464: Amplitude + Closure Phase Imaging
89453452: Bispectrum Imaging
74324712: CHIRP Imaging
21358612: PyMORESANE - cm- and metre-wave algorithm that is probably not ideal for EHT shadow imaging, but included here for comparison. More optimisation possible, as well as implementation as major loop in CLEAN-like algorithms.
