Topologies and handoffs

Calibrate camera networks and define topology graphs; hand off tracks using appearance, timing, and geometry. Use site maps to constrain associations.

Frequently asked questions

How does multi-camera tracking maintain continuous trajectories?

Multi-camera tracking links detections across multiple camera views to ensure that tracked objects remain continuously visible and follow consistent paths.

What are the key components of data association in this system?

Data association utilizes appearance embeddings, temporal priors (information about an object's past movement), and geometric constraints to accurately link detections across different camera views.

How do graph-based methods and probabilistic filters contribute to accurate tracking?

Graph-based methods and probabilistic filters help resolve ambiguities in object identities, particularly when objects are temporarily obscured or appear in crowded scenes. These techniques use mathematical models to manage uncertainty.

What types of analytics can be derived from the tracked data?

The system generates powerful analytical outputs such as route reconstruction (mapping an object's path), heatmaps (visualizing areas with high object density), and forensic search tools for investigating events.

Why is human-in-the-loop verification important?

Human-in-the-loop verification ensures that critical decisions made by the system are reviewed and validated by a human operator, improving accuracy and reliability.
