python人脸识别库
python3人脸识别的两种方法本文实例为大家分享了python3实现人脸识别的具体代码，供大家参考，具体内容如下
第一种：

import cv2import numpy as npfilename = 'test1.jpg" alt="python人脸识别库（python3人脸识别的两种方法）" border="0" />path = r'd:\face'def detect(filename): face_cascade = cv2.cascadeclassifier('haarcascade_frontalface_default.xml') face_cascade.load(path + '\haarcascade_frontalface_default.xml') img = cv2.imread(filename) gray = cv2.cvtcolor(img, cv2.color_bgr2gray) faces = face_cascade.detectmultiscale(gray, 1.3, 5) for (x, y, w, h) in faces: img = cv2.rectangle(img, (x, y), (x + w, y + h), (255, 0, 0), 2) cv2.namedwindow("vikings detected") cv2.imshow("vikings detected", img) cv2.waitkey(0)detect(filename) |
结果：
