OpenCV中的级联分类器Cascade Classifier（面部识别） OpenCV中的级联分类器Cascade Classifier

in this tutorial you will learn how to:

to detect objects in a video stream. particularly, we will use the functions:

load a .xml classifier file. it can be either a haar or a lbp classifer

perform the detection.

here is the result of running the code above and using as input the video stream of a build-in webcam:

remember to copy the files haarcascade_frontalface_alt.xml and haarcascade_eye_tree_eyeglasses.xml in your current directory. they are located in opencv/data/haarcascades

this is the result of using the file lbpcascade_frontalface.xml (lbp trained) for the face detection. for the eyes we keep using the file used in the tutorial.
