Facial recognition

From Computer Science Wiki
This a problem set for you to work through [1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

  1. to build your skill applying computational thinking to a problem
  2. to assess your knowledge and skills of different programming practices

What is this problem set trying to do[edit]

This is computer vision problem set. In this example we are learning computer vision, API's, and computer speech.

The Problem[edit]

Please design and build a system which utilizes a camera to detect faces as they enter our classroom. The system should recognize faces, and store faces with known-names. The system should say "hello <STUDENTNAME>" when they enter our classroom.

Unit Tests[edit]

  • User Input: The camera detects Mr. MacKenty entering the classroom.
