Reconstruction results from the noisy diffraction intensity . The five PR algorithms were given the same initial Fourier phase for fair comparison, and the total number of PR iterations in each algorithm was set to . In the ER + HIO algorithm, ER and HIO alternatively execute 150 iterations in each cycle until the maximum number of iterations is achieved. In the ER + KSVD and HIO + KSVD algorithms, KSVD is executed every 100 iterations .
