This is hardcoded in align_image_stack, it has the equivalent to
these hugin settings:
Local search area width: 100 pixels
Patch width: 20 pixels
..so my guess is that it will find points with ± 40 pixels
displacement (untested). I'm not sure that rotation search is
enabled so probably any rotation over 10° will result in
significantly less matches too.
Though recent versions downscale the image to 50% then divide it up
into a 5x5 grid - this has the potential to reduce the number of
matches with large displacement images, so I would try changing the
grid size (ie. add a '-g 2' parameter to align_image_stack) and see
if that makes any difference.
