LDEs [Eq. (1a)] of the automatic algorithm compared to expert Reader 1. Each box plot shows the distribution of LDE for a given landmark (see Fig. 1, for definitions) obtained in leave-one-out validation on 24 CBCT test images. The boxes represent the interquartile range (IQR), the vertical line is the median, the whiskers extend to the extreme data points within $\pm 1.5$ IQR of the median, and the dots are outliers.
