I have used SURF Keypoints and a FLANN Based matcher and plotted the matching Keypoints as circles and then drawn the rectangle grouping all the keypoints. As you can see, there are multiple vehicles matching the Template. I want to group the keypoints in a way such that I can get the count of the matching Vehicles. How can I go about doing this? I know that I can't just use a clustering method because, I need to group them more than just spatially.
