Hello everyone, This post makes me ask a question that's been bugging me for quite some time. I used to use autopano SIFT C for generating control points earlier by feeding it all the images at one time. But some time later i started sending two images at a time to the keypoint matcher with almost the same results. From my understanding, the matcher forms a tree of all the keypoints and uses an algorithm to find the nearest match for each such keypoint from within the tree. It matches not only adjacent images but images removed from each other too.
Which is the best approach? Is there really a need to match images which are not adjacent for good quality panoramas?
