Goal and impact
It was a pilot. The algorithm recognises whether a (moving) object is a human or not and determines the speed for each person. It then assigns a classification to this situation, such as "stationary", "agitated" or "panic". The aim is efficient enforcement on crowds. The algorithm is not intended to recognise people or do anything with personal data.
Considerations
It was an initial experiment to establish automated group dynamics rather than physically counting people. Citizens were filmed while on the promenade at the information point, after a few seconds the footage is deleted.
Human intervention
Yes, the enforcer. Camera and algorithm can be stopped at any time.
Risk management
A DPIA has been carried out (DPIA pressure measurement and group dynamics) describing the risks and measures. There is no bias as the dynamics are determined without preference on types of people. The choice of where to hang the cameras was made together with the enforcers.
Legal basis
Municipal Act. Section 172 Maintenance of public order (camera images) and Section 151C (processing camera images under police direction).
Elaboration on impact assessments
A DPIA has been carried out (DPIA pressure measurement and group dynamics) describing the risks and measures.

Camera footage.
Technical design
The algorithm detects people and their speed of movement. The algorithm recognises whether a (moving) object is a human or not and determines the speed for each person. It then assigns a classification to this situation, such as "stationary", "agitated" or "panic".

- In an expert examination, facial images are compared. The facial image comparison aims to determine whether a person visible in camera images (crime suspect) and the image of a known face (police photo of a suspect) are of the same person or two different people.Last change on 25th of June 2024, at 16:15 (CET) | Publication Standard 1.0
