TrackMetrics

UNIMPLEMENTED. Track matching model metrics for a single track match threshold and multiple label match confidence thresholds.

Fields
confidenceMetrics[] object (ConfidenceMetrics)

Metrics for each label-match confidenceThreshold from 0.05,0.10,...,0.95,0.96,0.97,0.98,0.99. Precision-recall curve is derived from them.

iouThreshold number

The intersection-over-union threshold value between bounding boxes across frames used to compute this metric entry.

meanTrackingAveragePrecision number

The mean average precision over all confidence thresholds.

meanBoundingBoxIou number

The mean bounding box iou over all confidence thresholds.

meanMismatchRate number

The mean mismatch rate over all confidence thresholds.

ConfidenceMetrics

Metrics for a single confidence threshold.

Fields
confidenceThreshold number

The confidence threshold value used to compute the metrics.

trackingPrecision number

Tracking precision.

trackingRecall number

Tracking recall.

boundingBoxIou number

Bounding box intersection-over-union precision. Measures how well the bounding boxes overlap between each other (e.g. complete overlap or just barely above iouThreshold).

mismatchRate number

Mismatch rate, which measures the tracking consistency, i.e. correctness of instance id continuity.
