如何在 Python 中使用 OpenCV 子模块？

Question

How to use createLBPHFaceRecognizer() in opencv3.3, and Python 2.7.13?

I Used Windows 64 bit OS

because i find an error in syntax :

import os
import cv2
import numpy as np
from PIL import Image

recognizer = cv2.createLBPHFaceRecognizer()
path='dataSet'

Error : recognizer = cv2.createLBPHFaceRecognizer()

AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'

You need compile OpenCV from source. Download both opencv and opencv_contrib .

In opencv_contrib source, there is a folder called modules , delete you don't use.

I don't how to compile it on Windows. There (OpenCV 3 Tutorials, Resources, and Guides) are some tutorials for install OpenCV(Linux, macOS, etc), but no Windows version. You can refer to relevant information for compile OpenCV from source on Windows.
