I m trying this bit of code. But always error for cv2.SIFT(). I m using python 3.6, windows 64 bit. I tried installing opencv contrib using anaconda prompt.
import cv2 import numpy as np
img = cv2.imread('home.jpg') gray= cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
sift = cv2.SIFT() kp = sift.detect(gray,None)
img=cv2.drawKeypoints(gray,kp)
cv2.imwrite('sift_keypoints.jpg',img)
SIFT and SURF were moved to opencv_contrib with opencv3, also the api changed:
>>> help(cv2.xfeatures2d) # new submodule
sift = cv2.xfeatures2d.SIFT_create()
surf = cv2.xfeatures2d.SURF_create()
you'll probably also need to update your cv2, and NOT use conda, but pip here:
pip install opencv-contrib-python
(the conda packages are badly maintained or outdated )
i did the pip install but it still says there is no module xfeatures2d module 'cv2.cv2' has no attribute 'xfeatures2d'

above code is only valid for outdated opencv2.4, so - which opencv version do you use ?
