No. FacePhi SDK does not work with images directly, but with a representation of the most important features of the image. Therefore, it is not possible to reconstruct an image of the user’s face.

No. The main recommendation is having a natural pose while looking at the camera.

No. The core of our FacePhi SDK system assures discrimination of impostors. Several tests have been made with twins and the system has never incurred in an error.

FacePhi SDK is distributed with a simple installer which will guide the user during the product installation.

It depends on the type of license you acquired. Usually FacePhi SDK is licensed for one device. This type of licensing validates the software installation in only one machine.

Minimum camera requirements:

  • 640 x 480 resolution
  • 24 fps or higher

Recomendado:

  • 640x480 resolution @30 fps or higher
  • Autofocus o Automatic Iris
  • Wide Dynamic Range Technology

In the product installation package you can find an application to activate the FacePhi software. This installer allows activating and installing licenses for the supplied serial numbers.

Currently FacePhi SDK is licensed individually for each machine. These licenses will depend on the type of application you wish to develop:

  • Windows license: for Windows applications.
  • Silverlight license: for Web Silverlight applications.
  • Android license: for Android and iOS applications.
  • WindowsLogon license: for applications integrated into the Windows login.

Lighting is a very important factor. If possible, light should be equally distributed over the face.

Visible shadows on the face should be avoided. This will occur especially when direct lighting is used or when there is backlighting in the captured scene. It is recommended avoiding these types of situations.

The required distance can be adjusted in the extractor. By default, in an image with a resolution of 640x480 pixels and a minimum distance between eyes of 70 pixels, the maximum distance from the camera is around 75 centimetres. Note that this may vary depending on the optical characteristics of the capture device (wide lens, zoom, etc.).

The system can be adjusted to work either in “multiface” or “monoface” mode. In the “multiface” mode, the system tries to detect all the faces in one image. In “monoface” mode, from all the detected faces, the system will work only with the largest size face (the one that appears closer).

Yes, but it depends on several factors. Situations where lighting causes reflects on the lenses should be avoided. If reflects could not be avoided, it is best if the glasses are removed for the capture process.

It is recommended that only clear, see-through glasses are used so that the eyes and iris are clearly visible.

Sunglasses are not accepted for their dark lenses, causing occlusion of the eyes.

FacePhi SDK tolerates moderate face changes due to ageing. However, if more radical changes occur, the system might not be able to correctly identify the user, having to enrol the user once again or retrain him/her.

Optimal position of the face is frontal or full face. Head movements should not overpass 15º degrees on each direction. These movements are the following:

  • Nodding up and down.
  • Turning right or left.
  • Tilting right or left.
