Binary classification

Hello,

If I want to do binary classification, which classifier do you suggest me? Random forest requires at least 2 vectors so I couldn’t do it.

I want to use S1, S2 and maybe include NDVI and GLCM to classify a type of tree among other trees and crops. So the idea is to have just two classess:
1-classified
2-non-classified

It is not mandatory to use SNAP, I can try in Erdas Imagine as well

thanks.
