TABLE 4.

Example of parameters calculated for an underestimated lumen area and an overestimated lumen area.

Area Prediction TP FP FN Precision Recall F1
Underestimated lumen area 1715 482 482 0 1233 1 0.28 0.44
Overestimated lumen area 85 600 85 515 0 0.14 1 0.25

When high precision is associated to low recall, then the area is underestimated. When the values are low for precision and high for recall, then the area is overestimated.
