#DOES MACCLEANER X ACTUALLY WORK VERIFICATION#

The accuracy of facial recognition depends on three main factors: lighting, pose and facial expression.

The computer then deducts whether the two images match (the deduction is based on the comparison score described above).

The created 3D map then goes through the processor's algorithms and is compared to the template that was stored in the phone's memory earlier.

The infrared images are transferred from the phone's camera to iPhone X's Neural Engine where a 3D map of the face is created.

Here's what happens during facial recognition on iPhone X: It is lower when you are just unlocking the phone (for instance, you can pass with a similarity score of 0,7) and higher when you are making a pricey purchase. The phone takes that into account and there is a different 'threshold' set for different scenarios.

Naturally, the verification image and the template image stored in the phone may have been captured under different lighting conditions. If it's close to 0, the verification process won't be successful. If the score approaches 1, the phone considers it as the same face and unlocks the phone. The computing then relies on the score from 0 to 1 to make the final verdict. When you want to unlock your phone, the phone will capture the image you are offering and compare it to the template of your face that has been set earlier. The patterns may be in the form of the waves of your voice, the structure of your iris or, in case of the iPhone X, the map of your face.

The system compares two patterns and tries to find similarities between them. The way all biometric authentication systems work is by comparison. Biometrics are also behind the modern tech's ability to read fingerprints, recognize voices and irises of the eyes. The technology that makes facial recognition possible is based on biometrics. How does the iPhone X recognize your face?

That's how all the details of your face are captured and mapped - but how are they later recognized when you want to unlock your phone.

The infrared camera captures images of the dot pattern and infrared light reflected from your face.

The dot projector produces enough light to create a 3D map of your face.

The flood light releases IR (infrared light) to illuminate your face (the light is invisible to the naked eye).

The TrueDepth camera (with the help of the proximity sensor and ambient light sensor) determines how much light is needed for correct facial recognition.

Here's what happens during image capture: The camera uses infrared light (IR) to light up your face, which allows Face ID to work under different unfavorable lighting conditions both indoors and outdoors: whether it's the lack of light or too much of it. You will be asked to move your face in a circle letting the camera take several pictures of your face and create a 3D map. All you need to do is follow the on-screen instructions. To enable Face ID, Apple uses its TrueDepth camera system: the two technologies work together to create a detailed map of the user's face.ДЄs with all Apple devices, setting up the new feature is quite straightforward. The technology behind uses a combo of light projectors and sensors to take pictures of your face - more specifically, facial features. Apple's Face ID works in much the same way as fingerprint recognition: it compares two facial images and deducts how similar they are.
