Best Face Detection Trained Data for Haar Cascade Classifier?

asked 2020-05-16 12:44:16 -0600

I'm trying to detect faces, however, some of the faces I want to detect are not perfect (some parts covered, not looking straight, head turned slightly). I used the default frontal face XML file provided by OpenCV, however, it gave many false positives, or the face wasn't detected at all. I was wondering if there was any other better-trained face detection data that could possibly have a more accurate detection rate trained with a Haar Cascade Classifier in XML format.

take a long look here, and try to imagine what happens in case of occlusion or pose variation:

those are indeed the limitations of using haar cascades. though good training data is very important, it's probably a better idea to use a cnn based method in this case, they're far more robust with problems like this
