How can I change the norm used by cv::FlannBasedMatcher?
Hi, I use the following code to create a cv::FlannBasedMatcher.
new cv::FlannBasedMatcher(new cv::flann::LshIndexParams(6, 12, 2));
How can I change the norm used by the matcher?
Thx
I am afraid that you cannot do that, if you see this documentation. You can instead do something about the
KDTreeIndexParams, orSearchParams. See this for more info.Basically there are these norm types defined in the cv2.NORM_L2,cv2.NORM_L1,cv2.NORM_HAMMING,cv2.NORM_HAMMING2. This documentation may help you : http://docs.opencv.org/trunk/doc/py_tutorials/py_feature2d/py_matcher/py_matcher.html
