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.

as far as i know,in case of a tree-based classifier several features are combined together to form a decision tree with the -maxDepth parameter to create a single feature.
