This thought crossed my mind today... I shoot w/ a pano head and carefully align my images w/ about 20% overlap. When APP creates keypoints, I assume that it searches the whole image.
Would it be possible to have an option for APP to only create keypoints 25% in from each of the borders? It would probably result in faster matching since all of the respective keypoints would be in the overlap areas. I've had to go to 200pts @ max a few times, but perhaps in a scenario like this I could get away w/ 30pts since all of them would be in the right places.
