How do humans recognise a face?
Probably, the neurons in their brain first identify the face in the scene (from person body and background), extract the facial features and by those features classify the person. We have been trained on an infinitely large dataset and infinitely big neural network.
Facial Recognition in machines is implemented the same way. First, we apply a Facial detection algorithm to detect faces in the scene, then extract facial features from the detected faces and use an algorithm to classify the person.
The workflow of a Facial Recognition system is as follows:
New tech brings new opportunities
Advancements in facial recognition have taken great leaps. But this is only the beginning of the technological revolution. Imagine how powerful the duo of facial recognition algorithms and chatbot technology.
It's never too late to become a part of this movement.
