Figure 4: The average value of uncertainty shown in Figure 1, as a function of the contrast-to-noise ratio. The circle mark shows the average value from zero to the Nyquist frequency (0–2.5 cycles/mm) and the rectangle mark is the average value up to the sampling frequency (0–5 cycles/mm), respectively
