人生苦短，我用python实现人脸（口罩）识别（几十行代码搞定）

import face_recognition
import cv2

#加载图片
image = face_recognition.load_image_file("image/LYF.jpg")
#识别图片上所有人脸的位置
face_locations = face_recognition.face_locations(image)
img = cv2.imread("1.jpg", cv2.IMREAD_COLOR)
for i in face_locations:
    #face_locations 返回参数位置说明 (top, right, bottom, left)
    top = i[0]
    right = i[1]
    bottom = i[2]
    left = i[3]
    # param 1:图片
    # param 2:左上角坐标
    # param 3:右下角坐标
    # param 方框颜色
    # 方框大小
    cv2.rectangle(img, (left, top), (right, bottom), (255, 255, 255), 2)
    # 显示图片
    cv2.imshow("1.jpg", img)
    # 保存为新文件
    cv2.imwrite("new.jpg", img)

cv2.waitKey(0)
cv2.destroyAllWindows()
