Question

什么是剂量误差->

  ret, im =image.read(); AttributeError: 'JpegImageFile' object has no attribute 'read'.

我正在从事图像处理工作，我编写了一个程序来检测人脸（在实时摄像头上），并且正在运行。我正在使用python2.7.12 code->

python

import cv2
import numpy as np
from PIL import Image
id=0
recognizer = cv2.face.LBPHFaceRecognizer_create()
recognizer.read('recognizer/trainner.yml')
cascadePath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascadePath);


cam = cv2.VideoCapture(0)
fontFace = cv2.FONT_HERSHEY_SIMPLEX
fontScale = 1
fontColor = (255, 255, 255)
while True:
    ret, im =cam.read();
    gray=cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
    faces=faceCascade.detectMultiScale(gray, 1.2,5)
    for(x,y,w,h) in faces:
        cv2.rectangle(im,(x,y),(x+w,y+h),(225,0,0),2)
        id,conf = recognizer.predict(gray[y:y+h,x:x+w])
        print(id)
        if id==2:
            id="mohan"
        elif id==3:
            id="krishna"
        elif id==4:
            id="satyam"
        elif id==5:
            id="Priyavrat"
        elif id==0:
            id="Unknown"





        cv2.putText(im,str(id), (x,y+h),fontFace,fontScale,fontColor)
    cv2.imshow('im',im) 
    if (cv2.waitKey(1)==ord('q')):
        break;
cam.release()
cv2.destroyAllWindows()

正在工作但是我想对特定图像使用此代码来检测面部，我将cam替换为图像地址.code->

import cv2
import numpy as np
from PIL import Image
id=0
recognizer = cv2.face.LBPHFaceRecognizer_create()
recognizer.read('recognizer/trainner.yml')
cascadePath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascadePath);
image = Image.open('dataSet/User. 1.14.jpg')


fontFace = cv2.FONT_HERSHEY_SIMPLEX
fontScale = 1
fontColor = (255, 255, 255)
while True:
    ret, im =image.read();
    gray=cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
    faces=faceCascade.detectMultiScale(gray, 1.2,5)
    for(x,y,w,h) in faces:
        cv2.rectangle(im,(x,y),(x+w,y+h),(225,0,0),2)
        id,conf = recognizer.predict(gray[y:y+h,x:x+w])
        print(id)
        if id==2:
            id="mohan"
        elif id==3:
            id="krishna"
        elif id==4:
            id="satyam"
        elif id==5:
            id="Priyavrat"
        elif id==0:
            id="Unknown"





        cv2.putText(im,str(id), (x,y+h),fontFace,fontScale,fontColor)
    cv2.imshow('im',im) 
    if (cv2.waitKey(1)==ord('q')):
        break;
cam.release()
cv2.destroyAllWindows()

我使用image = Image.open('dataSet/User. 1.14.jpg')选择图片但是此代码显示错误 >

  ret, im =image.read();
AttributeError: 'JpegImageFile' object has no attribute 'read

请任何人帮助我。

AttributeError：'JpegImageFile'对象没有属性'read'
