The image stabilization that I am familiar with over scan in each direction
by
40 pixels or so. They then compute the center mean intensity of the image
in each axis and adjust the start of line and start of scan line position
from
frame to frame.

The image stabilized binoculars use mechanical means (mass) to make
dynamic changes in the optical path.
