Edge Scene Graphs
DHI Labs · 2026
A layer between any detector and an alerting system that turns boxes into a queryable scene graph and explainable alerts.
- Spatial and temporal predicates, an interval-compressed graph, and a rule engine whose alerts point back to the evidence.
- 2.4 ms p50 per frame on-device; learned relation head R@20 0.500 against 0.220 for a frequency baseline on Visual Genome.

Cross-Camera Identity Memory
DHI Labs · 2026
Links people across cameras and answers questions like where someone went, from any tracker's event stream.
- Prefers leaving a link out to making a wrong one, and keeps a bounded memory that survives restarts.
- Zero wrong links across 7 cameras and 313 people on WILDTRACK; ships with a Frigate adapter.

Continual Open-Vocabulary Detection
DHI Labs · 2026
Add a new class on-device from a text prompt or a handful of image crops, with no gradient updates.
- A gate replays the site's evaluation set before a new class goes live, and classes can be rolled back.
- On COCO val2017, 4 of 6 added classes went live with zero forgetting of existing classes.

Predictive Alerting with a Falsification Ledger
DHI Labs · 2026
Forecasts incidents a few seconds ahead, explains each forecast by replaying it with a cause removed, and scores every forecast against what happened.
- A 210-scenario battery run through the production code, reported per alert type, including the weak one.
- 8% false alarms across the no-incident scenarios.
