In the installation instructions for Windows at [GoCV][1] we've the below line:

Download and run the MinGW-W64 compiler installer from https://sourceforge.net/projects/mingw-w64/?source=typ_redirect.

I downloaded the mentioned file, but could not find executor file, and could not find anything like x86_64-7.3.0-posix-seh-rt_v5-rev2 as mentioned in the instuctions, any help?

Current OpenCV versions do not support SIFT.

python3 example.py

returns

`Traceback (most recent call last):
File "example.py", line 90, in
points1, points2, intrinsic = dino()

pts1, pts2 = features.find_correspondence_points(img1, img2)

Currently pressing ctrl+c simply exits the program.
It would be nice if we can handle that and print something nice like Canceled by the user or something similar.
