If you are familiar with OpenCV library, you know what Haar Cascade image object detection is. By image object detection I mean, like human face detection or something else. I have some Haar Cascade XMLs for face detection, but I don't know how to create my own. I want to create Haar Cascade XMLs to detect simple bright circle light sources (i.e. flashing infrared light from TV remote control).

So, how do I create a Haar Cascade (.xml file) to use in OpenCV?

How to create CascadeClassifier :

  1. Open this link : https://github.com/opencv/opencv/tree/master/data/haarcascades
  2. Right click on where you find "haarcascade_frontalface_default.xml"
  3. Click on "Save link as"
  4. Save it into the same folder in which your file is.
  5. Include this line in your file face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_frontalface_default.xml")
