HAAR_SCALE_IMAGE not working #1

Closed melvin2204 closed 6 years ago

melvin2204 commented 6 years ago

Error: flags=cv2.cv.CV_HAAR_SCALE_IMAGE AttributeError: 'module' object has no attribute 'cv'

Windows 10 Python 3.4 CV 3.4.0

Removing that erroneous line fixed it for me, and it still works!

The legacy 'cv' submodule has been removed from OpenCV 3+. Also the name of the "CV_HAAR_SCALE_IMAGE" has been altered, along with some other things.

To fix the issue, change the following line: flags=cv2.cv.CV_HAAR_SCALE_IMAGE

With this line: flags=cv2.CASCADE_SCALE_IMAGE

That should fix the issue you're having. Also, I noticed that the code refers to the cascade file as "haarcascade.xml" even tough the name is "haarcascade_.xml" in the repository (notice the underscore). Add the underscore in your code, or change the filename to fix this as well.

I had to change "haarcascade.xml"to full path to it, like /home/username/simple_opencv_pi_face_detector/haarcascade.xml
