You all must have heard about the Apple’s iPhone X’s Face ID. It is one of the most famous applications of facial recognition application that lets users unlock their phones with faceprint mapped by the phone’s camera. Facial recognition has become a popular area of research in computer vision and one of the most successful applications of image analysis and understanding.
But what exactly is facial recognition? Facial recognition is a type of biometric software that maps an individual’s facial features mathematically and stores the data as a faceprint. There are various algorithms used by the software most recent and effective being deep learning. A dataset is made containing positive images of given individuals which are trained using the deep learning algorithm. Then the software uses the algorithm to compare a live capture or digital image to the stored faceprint in order to verify an individual’s identity.
