  1. IBM SVS Analytic Use Case Analysis Rick Kjeldsen

  2. Overview • This document shows fuel station cameras with proposed analytics that address requested use case scenarios. • Additional alerts are possible on many cameras including: • Night Loitering • where crime or vandalism is a possibility • Abandoned object • Where bombings or other terrorism are a possibility • Illegal Parking

  3. Rovinj cam 16 • Use case: Loitering • Alert on people who remain in store for long periods of time • Discussion • Loitering time has not been specified. • The longer the loitering time, the less reliable loitering detection becomes. Maximum practical loitering time is 1.5 to 4 minutes, depending on conditions. • Maximum loitering for a camera must be determined empirically. The provided video has no examples of loitering activity longer than 2 minutes. • Next actions • Work with customer to determine desired loitering time. • Provide video with several realistic examples of loitering longer than that time.

  4. Rovinj cam 16 • Use Case: Activity analysis • Activity over time • Histogram • Activity levels in different parts of store • Heatmaps or customer counts • Global or individual customer behavior patterns • Track Summary • Discussion • Any area of the store is suitable • Results will be approximate. Counting errors of at least 15% should be expected.

  5. Rovinj - cam 15 • Use cases • Drive-off detection • Provide alerts to the POS when cars arrive at or depart • Wrong direction • Detect if a vehicle enters the pump stations from the right • Car color • Record the color of any car in the region • Discussion • For Drive-off detection, POS must have ability to recover from both missing and false positive alerts.

  6. Rovinj - cam 15 • Use cases • Abandoned Object • Will have some false alerts due to cars at the pumps and objects moved in front of the building • Illegal parking • If applicable

  7. BS Litijska - cam 02 • Use cases • Drive-off detection • Provide alerts to the POS when cars arrive at or depart • Car color • Record the color of any car in the region

  8. BS Litijska - cam 03 • Use cases • Abandoned Object • Will have some false alerts due to shadows, parked cars and other transient activity • Illegal parking • If applicable

  9. BS Litijska - cam 04 • Use cases • Drive-off detection • Provide alerts to the POS when cars arrive at or depart • Car color • Record the color of any car in the region • Discussion • Information from top of image is unusable. Ignore to help avoid errors. Ignore

  10. BS Litijska - cam 05 • Use cases • Drive-off detection • Provide alerts to the POS when cars arrive at or depart • Car color • Record the color of any car in the region • Discussion • Cars partially out of alert RoI are not a problem.

  11. BS Litijska - cam 07 • Use cases • Illegal parking • Car color • Record the color of any car in the region • Loitering • Pre-empt vandalism

  12. BS Litijska - cam 10 & 11 • Use case: Loitering • Alert on people who remain in store for long periods of time • Discussion • Results are not likely to be good on cam 10: • Field of view convers only part of store • People often disappear behind racks • Much of usable area is line for counter, where loitering is expected. • Cam 11 will do somewhat better • Loitering is not detected when person moves between cameras

  13. BS Litijska - cam 10 & 11 • Use case • Person Search: Shirt color • Discussion • Forensic search for people based on their primary color (usually shirt color) • Currently one color per person • Next release (4.0) will have ability to search using multiple simultaneous color on both shirt and pants.

  14. BS Litijska - cam 10 & 11 • Use Case: Activity analysis • Activity over time • Histogram • Activity levels in different parts of store • Heatmaps or customer counts • Global or individual customer behavior patterns • Track Summary • Discussion • People disappear behind racks, especially in cam 10, making results less accurate. • Significant count and tracking errors are possible at any point in time, but longer term trends should be accurate.

  15. BS Litijska - cam 14 & 15 • Use Cases • Number of people behind counter • Excessive activity behind counter • Forensic search & alert on: • Shirt color of customers in line • Shirt color of clerk • Estimate line length (cam 15 only) • Global trends should be accurate, but significant momentary errors possible. • Activity patterns of clerk • Tracks • Heatmap • Time in front of register • Requires additional development

  16. Technical notes • Outdoor color search will work daytime only unless good lighting is available. • Abandoned bag alerts that overlap with parking zones may trigger an unacceptably high number of false alerts. • The accuracy of behavioral analytics, such as loitering, depends on the normal patterns of activity in the scene
