Managing "Anonymous Faces" in Recognition

Anonymous is classified by HIVO based on the following characteristics:

• Grouping by Characteristics: If someone’s face has been detected on an Asset but not labeled yet, they’ll be grouped with any other instances of the same detected characteristics.

• Automatic Tagging for Recognized Faces: If an Asset is uploaded and a face within it has already been tagged, then that upload will be automatically tagged with the given person.

• Minimum Appearance Threshold: To avoid cluttering results with faces from crowds, HIVO requires a face to appear at least 3 times across different assets before creating an "anonymous user."

Note: There may be false positives with detected faces, particularly when the detected faces are small, or if there’s items such as glasses or masks obstructing the face.

Action on Anonymous Faces

🔹 Step 1: Open Anonymous details page

Click on an anonymous person to see the Assets they’ve appeared in and edit their details.

Select Anonymous

🔹 Step 2: Open Action on Anonymous Menu

• The 3 dots icon will open the actions that you can take on the person

Show Edit Anonymous option

• The action menu will open, including the following actions:

  • Edit Details

  • Is this someone else?

  • Clear Regconition

  • Re-index Regconition

  • Delete Person

1. Edit Details action

• Name the detected face & optionally add a description or assign them to a User in your Client.

• Naming a face will label all Assets with the detected face at once.

2. Is This Someone Else?

Reassign all instances of this face to an existing person.

3. Delete Person action

• Delete the face from Recognition, including from the anonymous person list.

• This can be useful for faces that were incorrectly detected, or if they're not important (e.g. a spectator that’s appeared in multiple photos).

4. Clear Recognition action

Added a feature that allows users to delete all recognition data for a specific individual.

• Once executed, the recognition status for this profile will switch to OFF.

• The system will stop identifying this face based on the old underlying vector data.

5. Re-Index Recognition

This action will recreate missing vectors for the given person, so that the person can be matched in assets in the future.

• It can be used if the person’s vector data was previously cleared with the “Clear Recognition” action, or if the person does not have vector data to begin with.

• The action will keep vectors only for images that contain the one person. If multiple people are detected in one of the images that contain the person, then the vectors for the image will be deleted.

6. Person Recognition Re-indexing

If you want to reset and re-identify an individual as a completely new person, HIVO has added the "Enable Recognition for New Assets" option within the Edit Details section.

• Once activated, the system will treat all subsequent appearances as data for a new person.

• Users can conveniently access and toggle this option directly within the Edit Details of the Person profile.
