Use Compute_Descriptors on an existing vector<KeyPoint>? about akaze HOT 4 CLOSED

Hi,

In A-KAZE the descriptor is really attached to the detector. For being able to compute the descriptor you need to compute (or re-use the computations from the detector) the scale space. If you want to use a different detector and the descriptors from A-KAZE, you need to provide a way so that A-KAZE descriptors can be extracted from the scale space defined in the other detectors.

Ah I see. So if I was to:

AKAZE* evolutionDescrip;

//detect with evolutionDescrip in one function

evolutionDescrip->Compute_Descriptors(Keys, desc);

in another function, that would work?

Same instance of AKAZE, but in a different function.

thank you for your time.

It will work as long as you call Create_Nonlinear_Scale_Space(). However, keep in mind that when you use another detector in combination with A-KAZE descriptors you need to adapt the scale of the detected keypoints to an appropriate value for the descriptor computation.

Thank you. I have it working.
