Hello,
I'm trying to extract the orientation and scale from brisk's descriptors, but i don't know exactly how. I've already get the keypoints and the descriptors from my image.
Can anyone help me?
Thanks in advance,
Orientation and scale are stored in the Keypoint, they can be accessed by the angle and scale attritbute.
Thanks! Could you give me an example about how i do this in c++? I've already tried using "keypoint.angle" but it doesn't work. EDIT I mean, I just add the "types.hpp" in my code, but I still can't use it on my keypoints that I've extracted before with the BRISK constructor.
You need to add the whole OpenCV library, not types.hpp alone ... when creating a vector<Keyoints> collection; and then filling it with data by calculating keypoints, you can loop over them and access the angles using collection[i].angle which I just confirmed.
