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.
