    Lesson Outline

    Introduction to Face Detection - 15 minutes
    • Face Detection
    • How do we detect faces?
      • Knowledge based method
      • Feature based method
    Face Detection Blocks in PictoBlox - 10 minutes
    Activity 1: Face Expression Detector - 30 minutes

    In this project, students will make a script that detects the face using the camera and reports the expression of all the faces detected on the stage.

    How face recognition works - 15 minutes
    Activity 2: Face Recognition Project - 45 minutes

    In this project, student will make a script that saves the image of face in the memory and recognize the faces on the stage when implementing face recognition.
