Hello,
I'm trying to extract the scale from brisk's descriptors, but i don't know exactly how. I've already get the keypoints and the descriptors from my image.
I saw in another posts that I can get the size from the descripor wich is proportional to the scale in this way: size = scale * magnifier) but i need the scale value.
How can i get the scale value? Or the magnifier value?
Can anyone help me?
Thanks in advance,
