6. Today’s Demo - Motion Detection - Colour Detection

7. Motion Detection Yes!!! Computers can detect motions using cameras!
Remember basic maths? Like subtraction?
5 – 3 = ?
Well, it’s actually that simple!
The difference is your computer will do thousands or even millions of these calculations in less than a second.
It will subtract images/frames, like in a video or movie.

8. Motion Detection Let’s do a demo! All we need is: A computer
Few lines of code
A camera/webcam
A software that can run the code
And…… you or anything that moves 

9. Colour Detection Demo
We will use a different program (code) but the setup is the same. Find some Red, Green or Blue object in the room and wave it in front of the camera.
