dataeval.data.build_tracks¶

dataeval.data.build_tracks(source: dataeval.protocols.MultiobjectTrackingDataset) → collections.abc.Mapping[str, collections.abc.Mapping[int, dataeval.types.Track]]¶

dataeval.data.build_tracks(source: dataeval.protocols.MultiobjectTrackingTarget) → collections.abc.Mapping[int, dataeval.types.Track]

Build track dicts for a single target or an entire dataset.

Parameters:¶

source : MultiobjectTrackingDataset | MultiobjectTrackingTarget¶

A single target or a dataset containing multiple targets.

Returns:¶

If source is a target, returns mapping of track ID to Track. If source is a dataset, returns mapping of sequence ID to track mappings.

Return type:¶

Mapping[int, Track] or Mapping[str, Mapping[int, Track]]

Notes

MultiobjectTrackingTarget stores detections grouped by frame. This function inverts that structure so that each unique track ID maps to all of its observations across the sequence, in frame order.
