Hi @dgtlmoon This repository has not been updated for a while. The maintenance efforts are concentrated in the silx project (silx.image.sift). I'll update this repository when possible to keep it up to date with silx - I agree that the readme.md file should at least be updated.

The feature module was an optional dependency for the tests, to validate the implementation with respect to the ipol implementation of SIFT wrapped here. Unless you want to validate/compare sift_pyocl, this has little interest for actual image registration.

Instructions on how to run sift_pyocl are available on the silx documentation page.

If the transformation between the images to register is linear (translation, rotation, scaling, shear), you can also use the LinearAlign plan as follows.

import numpy as np
import scipy.ndimage as nd
from silx.image import sift
from scipy.misc import ascent

img = ascent()
angle_degree = 31.
shift = (27, 18)
img2 = nd.rotate(nd.shift(img, shift), angle_degree, reshape=False)
plan = sift.LinearAlign(img, devicetype="GPU")
img2_al = plan.align(img2)
