a few errors in feature matching articles

Please use OpenCV 3.x.. Those tutorials are not meant to be used with
OpenCV 2.x.

Hello, just tried your tutorial on python openCV (doing stuff on pattern
matching, and your articles are great!), yet met a few errors:

a call to cv2.LINE_AA causes an error - no-module-blah-blah… after
digging a little around cv2, found that it should be cv2.CV_AA.

Next culprit is img3 =
cv2.drawMatches(img1,kp1,img2,kp2,good,None,**draw_params) which returns module
object has no attribute 'drawMatches' and theres no drawMatches method in
dir(cv2)... couldnot resolve this one and google is of little help here.

using cv2 version 2.4.7
installed via macports and pip
osx

3.0 is it even released? can't find it anywhere...

You have to compile the source with master branch... download it from github.

Thanks! I think this issue can be closed then.

abidrahmank could you give me a quick walkthrough of how to compile the source from the master branch? I downloaded the 3.0 code but I'm not sure what to do next
