Web13 de out. de 2015 · Look for template-like keypoints in your scene by doing distance-calculations in M dimension : Each keypoint is like a point in 3D, and matching 2 keypoints as similar is nothing but calculating the distance of the points in 3D and saying "close enough "!. You now have 2 sets of keypoints, and a list of plausible keypoints matches. cttpark
