By face recognition, we mean the process that returns the position of the faces that are present in an image. In the Building a face detector using Haar cascades recipe, we already addressed this topic. In this recipe, we will use the face_recognition library to perform a series of operations on these faces.
The focal objective of face recognition consists of detecting the characteristics of a face and ignoring everything else that surrounds it. This is a feature on multiple commercial devices, and it allows you to establish when and how to apply focus in an image so that you can capture it. In the world of computer vision, it is customary to divide the family of face detection algorithms into two major categories. What distinguishes these two categories is their different uses of information, derived from a priori knowledge of the...
