At Standard AI, I built a novel algorithm to solve space and time association simultaneously for multi-camera multi-person tracking in stores of major retailers across North America, Japan and Italy.

  • Implemented 3D reconstruction, linear-program optimization, camera clustering & calibration, and hypergraph-based tracking.
  • Achieved a 40% accuracy increase and 15% speed increase over the previous module.
  • Added scalability that enabled deployment to 100+ stores of varying sizes.
