Head (and shoulder) detection using OpenCV

Question

(Appology in advance if I am asking a too nwbie question. I am a beginner with OpenCV. I have done some tutorials yet I have not a good grasp of it\'s concepts.)

Answer 1

Look at all the Haar boosted classifiers that are available with OpenCV and the dedicated class CascadeClassifier to use it. Here are a list of what the classifiers have locally:

• haarcascade_eye.xml
• haarcascade_lefteye_2splits.xml
• haarcascade_mcs_righteye.xml
• haarcascade_eye_tree_eyeglasses.xml
• haarcascade_lowerbody.xml
• haarcascade_mcs_upperbody.xml
• haarcascade_frontalface_alt.xml
• haarcascade_mcs_eyepair_big.xml
• haarcascade_profileface.xml
• haarcascade_frontalface_alt2.xml
• haarcascade_mcs_eyepair_small.xml
• haarcascade_righteye_2splits.xml
• haarcascade_frontalface_alt_tree.xml
• haarcascade_mcs_lefteye.xml
• haarcascade_upperbody.xml
• haarcascade_frontalface_default.xml
• haarcascade_mcs_mouth.xml
• haarcascade_fullbody.xml
• haarcascade_mcs_nose.xml

The two I bolded may be of special interest to you. Try those as a start for your project. As Alessandro Vermeulen commented, head detection classifiers may also be interesting, as what they find is usely connected to shoulders :-)
