Successfully solved the problem in python: AttributeError:'module' object has no attribute'LoadImage'

Problem Description

The source code is as follows:

import cv
from opencv.cv import *
from opencv.highgui import *

img = cv.LoadImage("test.jpg")
cap = cv.CreateCameraCapture(0)
while cv.WaitKey(1) != 10:
    img = cv.QueryFrame(cap)
    cv.ShowImage("cam view", img)
cascade = cv.LoadHaarClassifierCascade('haarcascade_frontalface_alt.xml', cv.Size(1,1))   

I get this error when I run the code:

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

Solutions

The reason for the problem: The "module" object has no attribute "LoadImage" .

Guess import cvand from opencv.cv import *this conflict, so try to comment f rom opencv.cv import *.

problem solved

When I changed the code to the following:

import cv
#from opencv.cv import *
#from opencv.highgui import *

img = cv.LoadImage("test.jpg")
cap = cv.CreateCameraCapture(0)
while cv.WaitKey(1) != 10:
    img = cv.QueryFrame(cap)
    cv.ShowImage("cam view", img)
cascade = cv.LoadHaarClassifierCascade('haarcascade_frontalface_alt.xml', cv.Size(1,1))    

Now the first error has been resolved and another error has appeared again.

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

Learned by searching information:

To load the haar classifier in OpenCV (in the python interface anyway) just use it cv.load.

as follows:

import cv
cascade = cv.Load('haarcascade_frontalface_alt.xml')
