Description

The Face Detection VL generates an event every time a face is captured in the frame.

The The Axxon One database  database stores all faces in binary form:

  1. All captured faces are stored as biometric vectors (
    2. see 
  2. see Face search) in
    3. the 
  3. the t_face_vector
    4.  table
  4.  table, and their corresponding capture events are stored in
    5. the 
  5. the t_json_event
    6.  table
  6.  table.
  7. All reference faces from the lists (see Faces) are stored in
    8. the 
  8. the t_face_
    9. listed 
  9. listed table.
Note
titleAttention!

When the number of faces in the database increases, the statistical error increases: the more faces in the database, the more often similar faces are recognized when searching in the archive. Accordingly, the degree of similarity when comparing the reference face with the captured face decreases.

This error is relevant if:

    The 
  1. The Video stream and scene requirements for the Face Detection VL and its sub-tools
    2.  are
  2.  are met.
  3. The database contains over a million faces.

Example of the error calculation results:

The mugshot dataset (good quality photo), 12 million faces in the database, and probability of false matching is 0.003%. With these initial data, the researchers obtained an identification error of 0.81%.

Add-ons

For the the Face Detection VL VL to work, you must install VL install VL Face Recognition Pack and VL SDK Pack (see Installing DetectorPack add-ons).

Note
titleAttention!

You can install only one Face one Face Recognition Pack: VA  VA Face Recognition Pack, VI Face Recognition Pack, TV Face Recognition Pack, or VL Face Recognition Pack. You cannot install several packages in the same system.
