I'm studying feature extraction and came across Scale-Invariant Feature Transform (SIFT) and I tried it in Pycharm
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)
The problem is I cannot find 'sift_keypoints.jpg' anywhere in my folders unless I comment out kp = sift.detect(gray,None)
then the file is there.
What am I missing / doing wrong?
When I run the code here is the result:
...Recognition.py
Process finished with exit code -1073741819 (0xC0000005)
it seems my problem was that sift = cv2.SIFT()
should be sift = cv2.SIFT_create()
.
can anyone explain why that was the problem?
i really thought kp = sift.detect(gray,none)
was the problem
