Image Registration Methods for Astronomy
(intended for extended emission, not stellar images!)
Documentation: http://image-registration.rtfd.org
Usage
pip install image_registrationorgit clone https://github.com/keflavich/image_registration
from image_registration import chi2_shift
from image_registration.fft_tools import shift
import image_registration
#Generate Sample Image
image = image_registration.tests.make_extended(100)
offset_image = image_registration.tests.make_offset_extended(image, 4.76666, -12.33333333333333333333333, noise=0.1)
#Get Fused Image
xoff, yoff, exoff, eyoff = chi2_shift(image, offset_image)
corrected_image2 = shift.shiftnd(offset_image, (-yoff, -xoff))
