How to get the coordinate from "class KeyPoint"?
The following is my code.
std::vector<KeyPoint> keypoints_object, keypoints_scene;
detector.detect( img_object, keypoints_object );
detector.detect( img_scene, keypoints_scene );
I'm trying to get the coordinate in the keypoints_object & keypoints_scene to store in another variable. Does someone know how to do it? (PS:My opencv version is 2.4.2)
