Now that you know how to track different things using the framework, you can try tracking your nose, mouth, and ears as well. Let's use a nose detector to overlay a funny nose on top:
You can refer to the code files for a complete implementation of this detector. There are cascade files called
haarcascade_mcs_rightear.xml that can be used to track the different face parts. So, you can play around with them and try to overlay a moustache or Dracula ears on yourself!
