Is it possible to have a few data points as support vectors while they are far from the plane?

We know that in SVM, support vectors that determine the position and orientation of the hyperplane are close to the boundary (close to the plane). In the simulation I did most of the support...

Is there any advantage in multiclass classification compared to binary classification if both are possible?

Multiclass data can be divided into binary classes. e.g. you have 3 classes of data named: A, B, C. You can do multiclass classification or you can divide them into the binary groups like: A-B,...

I do not have a function like that, but you can try extract the co-ocorrence matrix in 3D using the displacement as a 3D function D(x,y,z) instead of just D(x,y) and computing the Haralick descriptors. There is a related paper here you may check out: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.69.5262&rep=rep1&type=pdf

In Gonzalez and Woods (3rd edition) book, there is a full description of the Co-occurrence matrices, the Haralick features and tips on how to compute it faster.

Matlab code available here:

This takes a GLCM as input. Best of luck.
