Description

When trying to run Brute-Force Matching with SIFT Descriptors and Ratio Test in the Feature Matching tutorial, I needed to update ‘sift = cv2.SIFT’ to instead read ‘sift = cv2.xfeatures2d.SIFT_create()”

After making that change and trying to run the example, I get the following error.

img3 = cv2.drawMatchesKnn(img1,kp1,img2,kp2,good,flags=2)
TypeError: Required argument 'outImg' (pos 6) not found

I’m not sure what is needed here instead of ‘flags=2’. Please advise.
