Figure 4.

Evaluation of the segmentation performance for a varying number of motion cycles. The dashed line shows the percentage of pixel in the segmentation that was additionally marked as motion affected although being motionless. The dotted line shows the percentage of pixel that was falsely segmented as motionless, although being in the motion affected region. The black line shows the corresponding rotation speed for 360°, assuming a fixed motion frequency of $0.25\mathrm{Hz}$. In the dashed region, the segmentation quality is degraded.
