Code for testing that you have access to SIFT, SURF, and other keypoint detectors and local invariant descriptors. Reference: Adrian Rosebrock's blog post @ https://www.pyimagesearch.com/2015/07/16/where-did-sift-and-surf-go-in-opencv-3/
# Test code is from Adrian Rosebrock's blog post @ https://www.pyimagesearch.com/2015/07/16/where-did-sift-and-surf-go-in-opencv-3/
import cv2
image = cv2.imread("test.png")
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
# SIFT features
sift = cv2.xfeatures2d.SIFT_create()
(kps, descs) = sift.detectAndCompute(gray, None)
print("# kps: {}, descriptors: {}".format(len(kps), descs.shape))

# Read test image and show it
img = cv2.imread('test.png')
cv2.imshow('Window', img)
