Facial Recognition​

Facial recognition accuracy (NIST Standards)​

The table below shows Face SDK quality metrics based on the National Institute of Standards and Technology (NIST) Standards:

NIST Face Recognition Vendor Test (FRVT) 1:1Score
VISA* True Acceptance Rate (@FAR 1E-6)99.70%
Mugshot* True Acceptance Rate (@FAR 1E-5)99.76%
Border* True Acceptance Rate (@FAR: 1E-6)99.75%
WILD* True Acceptance Rate (@FAR 1E-4)96.94%
Click here to see the description of image types from the table*
  • VISA – Full Frontal image type. The images have a size of 252x300 pixels. The mean interocular distance (IOD) is 69 pixels.
  • Mugshot – Full Frontal image type. The images are of variable sizes. The mean IOD is 113 pixels.
  • Border – The images are taken with a camera, which is oriented by an attendant toward a cooperating subject. This is done under time constraints so there are role, pitch and yaw angle variations. Background illumination is sometimes strong, so the face is under-exposed. There is some perspective distortion due to close range images. Some faces are partially cropped.
  • Wild – The images include many photojournalism-style images. Resolution varies very widely. The images are very unconstrained with wide yaw and pitch pose variation. Faces can be occluded, including hair and hands.

Facial recognition accuracy on extended LFW dataset with Wild images​

For this test we used extended LFW dataset (LFW dataset + our internal dataset). The set of mismatched pairs was increased and LFW errors were fixed to get accurate measurements at low FAR.

* – characteristics specified in this table are given for a single-core CPU.
** – template extraction time when processing_less_memory_consumption was set to true in the FacerecService.createRecognizer call for creating a Recognizer.
*** – template extraction time using the AVX2 instruction set (see Facial Recognition).

Note:

  • Accelerated search time is given for k=1. As for larger values of k, the time will increase up to the search time without acceleration.
  • Accelerated search is implemented only for the recognition methods 6.5, 6.6, 6.7, 7.3, 7.6, 7.7, 8.6, 8.7, 9.30, 9.300, 9.1000, 10v30, 10v100, 10v1000, 11v1000, 12.30, 12.50 , 12.100, 12.1000.
  • To achieve this speed, the templates in the index must be located in order of creation (by using the Recognizer.processing or Recognizer.loadTemplate method).
  • To achieve higher speed, use GPU (see GPU Usage).
