cv2.lbphfacerecognizer 没有属性 'load' 'predict'

Question

import cv2
import numpy as np
faceDetect=cv2.CascadeClassifier('haarcascade_frontalface_default.xml');
cam=cv2.VideoCapture(0);
rec=cv2.face.LBPHFaceRecognizer_create();
rec.load("recognizerr\trainingData.yml")

id=0

fontface=cv2.FONT_HERSHEY_SIMPLEX

while(True):

    ret,img=cam.read();
    gray=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
    faces=faceDetect.detectMultiScale(gray,1.3,5);
    for(x,y,w,h) in faces:
        cv2.rectangle(img,(x,y),(x+w,y+h),(0,255,0),2)
        id,conf=rec.predict(gray[y:y+h,x:x+w])
        if(id==1):
            id="Name"
        else:
            id="Unknown"    
        cv2.putText(img,str(id),(x,y+h),fontface,2,(255,0,0),3);
    cv2.imshow("Face",img);
    if(cv2.waitKey(1)==ord('q')):
        break;
cam.release()
cv2.destroyAllWindows()

面对 rec.load 中的错误追溯（最近一次通话最后一次）：

File "C:\Users\DELL PC\Downloads\faceDetec_YOUTUBE-20171021T212250Z-001\recognize\detector.py", line 7, in rec.load("recognizerr\trainingData.yml") AttributeError: 'cv2.face_LBPHFaceRecognizer' object has no attribute 'load'

Answer 1

我正在使用 python 3.6.3 和 openCv 3.3 并面临同样的问题。在 openCV 3.3 中删除了 load() 和 save()。 load() 替换为 read() 并且 save() 替换为 write()

Answer 2

使用：

rec=cv2.face.LBPHFaceRecognizer_create();

Answer 3

在 OpenCV 3.3 中

load() 替换为 read()

save() 替换为 write()

Answer 4

在openCV==3.x

load() is replaced with read() 
save() is replaced with write()

cv2.lbphfacerecognizer 没有属性 'load' 'predict'

cv2.lbphfacerecognizer has no attribute 'load' 'predict'

python

load

predict
