We utilize the Hungarian Algorithm to associate new detections with existing poly tracks based on Intersection over Union (IoU) of the predicted polygons. $$ Cost_i,j = 1 - IoU(Poly_i, Poly_j) $$ If $Cost_i,j < \textThreshold$, the tracks are merged in the import buffer.
Services like AfterShip or Tracktry use import codes in their batch endpoints. A POST request to /v1/trackings/import might require a poly_code field that concatenates carrier_slug + tracking_number + customer_tag . This prevents duplicate entries and enables partial updates. poly track import codes
The "Poly" representation reduces the data payload by approximately 90% compared to storing raw point clouds, as only 4-8 vertices are stored per object per frame. We utilize the Hungarian Algorithm to associate new
