Hi,

I use ORB for a project and I need to understand how it works.

I don't understand all the parameters of ORB constructor, can you help me ?

I need to optimise time of research / precision

Parameters :

  1. nfeatures : number of keypoints,more keypoint increase time of research
  2. scaleFactor : lower (close to 1.0f) increase precision and increase time
  3. nlevels : number of level of pyramids. Don't understand how that affect time or precision
  4. edgeThreshold size of the keypoint ? Don't understand how that affect time or precision
  5. patchSize need to match edge ???

Thanks.
