Dear All,
I made a program (python then converted as exe for free distribution) that makes use of opencv image matching and I run into a problem.
I compiled opencv3 to have also akaze, brisk and so on and I normally subsample the images to 800x800 pixels.
The problem is that when I want to try an image matching with larger images, the only feature descriptor that allows me to rise the image limit (up to 3600 x 3600) is Brisk-Flann.
Did I do anything wrong with SIFT, SURF, ORB and AKAZE that doesn't let me (I mean that it crashes for lack of memory) to use larger images?
I cannot imagine where to start searching in order to solve this problem.
Any help would be more than welcome.
Thanks
