Overview

In this lesson, you’ll be learning about face detection in real-life projects. We will be creating an activity based on face expression detection using Pictoblox that detects the expression of the face analyzed and commands the Tobi sprite to speak the expression detected. Watch the video for a step-by-step guide to making the “Face Expression Detector” activity within PictoBlox.

Introduction to Face Detection

In the past few years, face recognition has become one of the most promising applications of computer vision. Face detection can be considered to be a substantial part of face recognition operations.

The method of face detection in pictures is complicated because, well, human faces are widely different from one another! They can have different poses, expressions, positions, orientations, skin color, glasses or facial hair or not, etc. Then are also differences in camera gain, lighting conditions, and image resolution.
