Description: Astrometric registration of images when no WCS info is available
Astroalign is a Python module that will try to align two stellar
astronomical images, especially when there is no WCS information
available.
.
It does so by finding similar 3-point asterisms (triangles) in both
images and deducing the affine transformation between them.
.
Generic registration routines try to match feature points, using
corner detection routines to make the point correspondence. These
generally fail for stellar astronomical images, since stars have very
little stable structure and so, in general, indistinguishable from
each other. Asterism matching is more robust, and closer to the human
way of matching stellar images.
