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.
