# (Astronomical) Image Registration¶

Github: Image Registration

TL;DR version

Use chi2_shift to match images.

A toolkit for registering images of astronomical images containing primarily extended flux (e.g., nebulae, radio and millimeter maps). [*]

There are related packages scattered throughout the internet that do the same thing, but with different features.

The general goal is to align images that look kind of like these:

## Module APIs:¶

image_registration Package

fft_tools Package (and a description of the Fourier Image Manipulation Tools)

tests Package

The most successful of the methods implemented here is chi2_shift

There is an ipython notebook demonstration of the code here and in pdf here

# Indices and tables¶

 [*] Apparently astronomical images look a lot like microscopic images. So maybe this code is good for coaligning bacteria!
