Hi, I want to use the extended parameter for Surf algorithm. Here is my code :
SurfFeatureDetector detector2(minHessian);
detector2.extended=1;
and then
extractor2.compute(img, keypoints_4, descriptors2);
cout<<"descriptors2 "<<descriptors2.rows<<" + "<<descriptors2.cols<<endl;
and the result is:
descriptors2 168 + 64
but I want my Surf descriptor to have 128 columns with extendedparameter. How is it possible to do this?
Thanks
