FFT based image registration
Imreg is a Python library that implements an FFT-based technique for translation, rotation and scale-invariant image registration .
|Organization:||Laboratory for Fluorescence Dynamics, University of California, Irvine|
Imreg is no longer being actively developed.
This implementation is mainly for educational purposes.
An improved version is being developed at https://github.com/matejak/imreg_dft.

>>> im0 = imread('t400') >>> im1 = imread('Tr19s1.3') >>> im2, scale, angle, (t0, t1) = similarity(im0, im1) >>> imshow(im0, im1, im2)
>>> im0 = imread('t350380ori') >>> im1 = imread('t350380shf') >>> t0, t1 = translation(im0, im1) >>> t0, t1 (20, 50)
