class DetectionResults(BaseClassificationResults): (source)

Known subclasses: fiftyone.utils.eval.activitynet.ActivityNetDetectionResults, fiftyone.utils.eval.coco.COCODetectionResults, fiftyone.utils.eval.openimages.OpenImagesDetectionResults

View In Hierarchy

Class that stores the results of a detection evaluation.

Parameters
samples	the `fiftyone.core.collections.SampleCollection` used
config	the `DetectionEvaluationConfig` used
eval_key	the evaluation key
matches	a list of `(gt_label, pred_label, iou, pred_confidence, gt_id, pred_id)` matches. Either label can be `None` to indicate an unmatched object
classes	the list of possible classes. If not provided, the observed ground truth/predicted labels are used
missing	a missing label string. Any unmatched objects are given this label for evaluation purposes
custom_metrics	an optional dict of custom metrics
backend	a `DetectionEvaluation` backend
