# How to choose the coefficients for a Surface LaPlacian filter (spatial filter)?

I'm trying to read up on the Surface LaPlacian filter/transform to better understand what this is all about. However, if someone wants to explain what I need to know to continue learning OpenViBE that would be greatly appreciated

In the OpenViBE classification examples, they have this spatial filter labeled LaPlacian Surface. It takes 2 coefficients for every 1 input channel as parameters. I am wondering how one goes about determining what coefficients to use.
