I would like to have an estimate of how fast it is to run an image registration algorithm on two HD images in Python. The registration needs to be very robust, too. Ideally running within under a second. I found a few library and did some tests (such as using cv2's first code snippet in this page), however results were disappointing.
For example, it did not work on the two following images, trying to fit the second one on the first one:
Would anyone know a fast algorithm that is robust, callable from Python? What about speedups related to image resolution? Ideally I would use HD images. I also found this, but did not got the time to test it: http://pyimreg.github.io/
