Faces Recognition

If you configured and deployed Faces Recognizer service, it will start feeding recognized face classes (clusters) int Faces Archive. Faces Recognition UI page allows viewing and managing data stored in Faces Archive.

Definitions

To make the rest of explanations more comprehensible, we will lead with a few definitions:

• Face Class: set of detected faces that were clustered into one category by similarity and considered belonging to the same person / subject.
  • each Face Class has UUID
  • each Face Class member is represented by 96x96 image of detected face
  • multiple members allow better accuracy since faces of the same person can be detected under different lighting and from different angles
• Unknown Faces: face classes that were not assigned any specific identity
• Known Faces: face classes with assigned identity, which is represented by:
  • Full Name
  • Distinguished Name (useful for company directory integration)
  • Face Group (see definition below)
• Face Group: known faces are assigned to face group (such as: Family, HR staff etc.) to create structure / hierarchy

Tree View

On the left side of the Faces Recognition page, tree view shows all face classes stored in the archive. Two top level folders are:

• Unknown: list of unknown face classes
• Known: groups of known face classes

Face classes can be deleted with context menu of tree node.

Unknown Face Classes can be registered as known:

• Right-click on Face Class under Unknonw Faces folder
• Choose “Register” -> registration card will be displayed
• Fill in the following:
  • Full Name
  • Distinguished Name
  • Choose existing or create new Face Group
• Click “Register” -> Face Class will move to Known Faces branch.

Known Faces can be unregistered:

• Right-click on Face Class under the Known Faces branch
• Choose Unregister -> Face Class will move to Unknown Faces branch

When selecting Face Class from any branch, UI will download and display all facs’ thumbnails that represent selected Face Class. Reviewing these images, you can identify a person and, if needed, define your further course of action (registering, unregistering, deleting)
