#All flags profile photo converter code

While loading In, in expression starting on line 22 Seems tricky to me because None in Python and nothing in Julia do not appear to behave the same way.Īnything else I could try? What could the problem be, and how can I fix it? Img3 = cv2.drawMatchesKnn(train,kp1,query,kp2,good,nothing,flags=2) SystemError('NULL result without error in PyObject_Call',) Img3 = cv2.drawMatchesKnn(train,kp1,query,kp2,good,0,flags=2)Īnd got this error: LoadError: PyError (:PyObject_Call) This: (passing the scalar value 0, which worked for the method drawKeyPoints() in another program) TypeError('Required argument 'outImg' (pos 6) not found',) Img3 = cv2.drawMatchesKnn(train,kp1,query,kp2,good)Īnd got this error: (so arg6 is required) LoadError: PyError (:PyObject_Call)

I'm having problems because I don't really know what an equivalent, working example in Julia would be. Img3 = cv2.drawMatchesKnn(train,kp1,query,kp2,good,None,flags=2) (the key argument is argument 6, specified as 'None') Possible flags bit values are defined by DrawMatchesFlags.Īs you can see from the sample program, the drawMatchesKnn() line in Python would look like this:

flags – Flags setting drawing features.

If the mask is empty, all matches are drawn.

matchesMask – Mask determining which matches are drawn.

If singlePointColor=Scalar::all(-1), the color is generated randomly.

singlePointColor – Color of single keypoints (circles), which means that keypoints do not have the matches.

If matchColor=Scalar::all(-1), the color is generated randomly.

matchColor – Color of matches (lines and connected keypoints).Its content depends on the flags value defining what is drawn in the output image. matches1to2 – Matches from the first image to the second one, which means that keypoints1 has a corresponding point in keypoints2].keypoints2 – Keypoints from the second source image.keypoints1 – Keypoints from the first source image.Python: cv2.drawMatchesKnn(img1, keypoints1, img2, keypoints2, matches1to2]]]]) → outImg

I have an example of the code I want to use in Python (see Brute-Force Matching with SIFT Descriptors and Ratio Test in this link: for the full Python code.)Įverything up to the point of drawMatchesKnn() works fine, but I have issues with the outImg argument when converting to Julia.ĭocumentation for drawMatchesKnn() is pasted below: Make sure you click 'Apply.'
