What is AFR?

Automated Facial Recognition is software that can automatically detect faces in an image or video and compare with a database of facial images.

Operationally it used to:


  • Match real time CCTV to a watch list of persons of interest and alert when detected and:

  • Compare a crime scene image (e.g. CCTV still) to a large database of images such as a custody set of images.

AFR can not be used to identify persons unless they are in a watchlist.

We are able to deploy AFR at the biggest events across South Wales.

AFR greatly assists us by allowing resources to be deployed elsewhere in protecting our communities.

How AFR works

AFR is made up of two parts, Identify & Locate. Which work together to help search for people.

Identifying graphic

Identify

AFR Identify is ‘Slow-time’ application of AFR technology, comparing still images of unknown suspects and persons of interest , against a custody database of circa 500,000 people, and returning up to 200 results.

Prior to AFR Identify identification of a suspect typically took two weeks to achieve. The same result can now be achieved the same day.

  • The process combines cutting edge technology and an experienced identification officer to make a possible match.
  • Has been used to assist in the identification of hundreds of suspects across South Wales and more recently assisted in identifying the most vulnerable in our communities.

Locate

AFR Locate is ‘Live-time’ deployment of AFR technology, which compares live camera feeds of faces against a predetermined watchlist in order to ‘locate’ persons of interest. This generates possible matches that are reviewed by the operator(s).

  • Faces that are not matched against the watchlist are not remembered or kept.
  • Watchlists are unique for each deployment.
  • People not featured in a watchlist can't be identified.
