Thank you for your work! It is a very informative project. I receive the subject line error when attempting to stitch images of a paved runway. Attached is a sample image. Changing the 'scale' or the MIN_MATCH_COUNT variables does not help. Does the image need more protrusion features for the algorithm to work properly? Is there a certain format or size of images required?

Thanks!
