Figure 5
The extracted contrast values from different algorithms at fixed count rate photons per pixel for both nominal gain variation σg = 0.5% and ten times larger σg = 5%. The gray dashed line indicates the correct solution. The three lines are fitted to extracted contrasts for σg = 5% using LSF, GG and PPC and their slopes are 1.2 ± 0.1, 0.87 ± 0.08 and 0.65 ± 0.07, respectively. |
