In http://docs.opencv.org/3.0.0/d1/d73/tutorial_introduction_to_svm.html there exists an example of SVM.
The expected result image is:
There are gray circle around three support vectors.
But after implement the example, the image I got is:
There is no gray circle around any support vector. Only a quater of gray circle appeared at top left corner.
What is the problem ?
My environment is as follows: Windows 10, Visual Studio 2013, opencv-3.0.0。
