In the Opencv there are some haar cascades:
- haarcascade_frontalface_alt.xml - Stump-based 20x20 gentle adaboost frontal face detector. Created by Rainer Lienhart.
- haarcascade_frontalface_alt2.xml - Tree-based 20x20 gentle adaboost frontal face detector. Created by Rainer Lienhart.
What is the difference between Stump-based and Tree-based frontal face detector? Inipractice, they give very similar results.
