Storing ORB Keypoints in file
I need to store ORB keypoints and descriptors inside some file, and am currently using Pickle but it is slow (~10-15 seconds to load). Is there another way that would allow for faster saving and loading?
I tried using JSON before but could not serialize the objects (since they are complicated). Could anyone provide insight?
opencv version ?
Using 3.0.0
ah, shame, so you can't use cv2.FileStorage (requires 3.2 or 3.1)
also, why do you need this ? (what are you trying to do ? need to store keypoints sounds a bit weird)
