Figure 5: FD vs. fFD relationship in the PIB-PD dataset.

Figure 5:

(A) Proportion of frames below an FD threshold of 0.2 (x-axis) or an fFD threshold of 0.1 (y-axis). Black line is unity. Note that most points lie above the black line, indicating data savings despite a lowered fFD threshold. (B) The differences in frames retained between the FD<0.2 and fFD<0.1 is related to the amount of HF-motion (y-direction) in a given participant. (C) The similarity between censoring masks created from the fFD<0.1 threshold and the FD<0.2 threshold is related to the amount of HF-motion in a given participant. Participants exhibiting low levels of HF-motion show the most similar censoring masks.
