i have an image where i want to remove the center only. how can i do so?
i played around with this tutorial. at first i found a match but that was when i used 2.4. I switched over to 3.0 and even if i followed the tutorial and changed some syntax for 3.0, it doesnt find the right match.
the only things ive changed from the tutorial is
// this
SurfFeatureD`enter code here`etector detector( minHessian );
// to this
Ptr<SurfFeatureDetector> detector = SURF::create(minHessian);
//and this
SurfDescriptorExtractor extractor;
// to this
Ptr<SurfDescriptorExtractor> extractor = SURF::create();
where
int minHessian = 400;
im not sure if im instantiating it right or not. thanks in advance!
