Tutorial on Registering Images
This tutorial shows you how to register an image set using Mira's Image
Registration package. If the alignment involves correcting a simple field drift or a
wobble, then you can align them using a simple "shift" alignment on 1 or more points.
However, in this example we will need the full power of the Register Images command
because one of the images has has a serious parallelogram distortion. The pictures
below show the 4 images averaged to show the same stars at various locations in
the images. Within each picture, each group of points shows the same star from
each of the images. It is clear that the images cannot be brought into alignment
using any combination of shifting, scaling, and rotation. However, Mira has the
tools that will solve this problem.
