Great work, can you provide the source code for reproduction?

I am also working on the related inverse problem imaging, but recently I am stuck on the SISSY algorithm, it always does not converge, if you can provide the source code of this simulation, I would be very grateful!

The code for the SISSY algorithm is in the file sissy.m
This function is used for the simulation in the main code inverse_problem.m file.
I added theoretical explanations of this algorithm in the Readme to make the code more understandable.

Thank you. I tried your SISSY simulation, but it also did not work well on my data set. I found that the effect may be better than expected under the L1, 2 norm constraint in the SISSY paper.
