Global Association Multicamera Tracking

The Global Association Multicamera Tracking filter links object identities across several camera streams, so an object seen by one camera and later by another is recognised as the same object rather than as two unrelated tracks.

Features

• ReID embeddings — associates identities by appearance rather than by position alone, so a gap in coverage does not break the track.
• Temporal gating — bounds how far apart in time two observations may be and still be considered the same object.
• Configurable transition maps — encodes which camera an object can plausibly move to next, so impossible associations are rejected.

Use cases

• Following a subject across a multi-camera site with non-overlapping fields of view.
• Building a single timeline of an object's movement from several independent streams.
• Counting unique objects across a camera network without double-counting.
