Figure 6
Comparison of computational time. (a) Computational time (s) versus the number of iterations. (b) FRC at a spatial frequency of 18.75 µm−1 versus computational time (s). The blue, green and yellow lines correspond to ePIE, rPIE and PINE, respectively. The dashed and solid lines in (b) represent the results for the low-dose and high-dose data, respectively. |
