Face lock system in smartphones is an example of Computer Vision. 

Explanation:-

Computer Vision is one of the three domains of AI. It gets the visual data and analyses them to make a decision. 

This process includes acquiring images, screening, analysing, identifying and extracting information. In computer vision, input to the machines are photographs, videos taken from thermal, or infrared sensors, indicators and other sources.

In this process, the visual data can be translated into descriptions and turned into computer-readable language to make a decision.

Now let's take a look at the working of the face lock system :-

  1. Face lock system in a smartphone detects and capture the image.
  2. It saves the features of the face at the beginning or first time when the lock is applied.
  3. After than whenever the features matched it will unlock the smartphone.
