Error around detectAndComputer method in openCV python code

I'm using python 3.6.3, opencv-contrib-python-3.3.1.11 in VS Code. I'm trying to run the following code:

import cv2
image1 = cv2.imread('PATH.image1.jpg',0)
image2 = cv2.imread('PATH.image2.jpg',0)

sift = cv2.xfeatures2d.SIFT_create()

kp1, des1 = sift.detectAndComputer(image1,None)
kp2, desc2 = sift.detectAndComputer(image2,None)

I've read about the change in SIFT for earlier versions of openCV and the later versions making a user install the opencv contrib instead. My error isn't around the create but rather around the detectAndComputer method. This is the error:

Exception has occurred: AttributeError
'cv2.xfeatures2d_SIFT' object has no attribute 'detectAndComputer'
Solution

  • The correct call is kp1, des1 = sift.detectAndCompute(image1,None) rather than detectAndComputer.

    There are some details on this process and code syntax here
