Matching Predictions to Ground Truth: TP, FP & FN at IoU ≥ 0.5
This lesson is part of the course
In this lesson
You match 12 person detections on four frames to the 10 labelled persons, greedily by confidence: TP if IoU ≥ 0.5 and the ground truth is still free, otherwise FP; then count the missed persons (FN), precision and recall.
