Can’t use SURF, SIFT in OpenCV

by

There is a pip source that makes this very easy.

  1. If you have another version of opencv-python installed use this command to remove it to avoid conflicts:

    pip uninstall opencv-python

  2. Then install the contrib version with this:

    pip install opencv-contrib-python

  3. SIFT usage:

    import cv2
sift = cv2.xfeatures2d.SIFT_create()
