Calculating/utilizing surface Laplacian coefficients
Posted: Mon Dec 23, 2019 12:56 am
Hi All,
I've been trying to find a clear example of how to calculate and use new coefficients for the surface Laplacian filter in the example motor imagery project for some time now, with no clearer explanation than that found in the documentation for the spacial filter box. Perhaps I don't understand the math necessary to create new coefficients. I want to limit the number of input channels to 6 (focused specifically on C3 and C4, but with input from Fp1, Fp2, F3, and F4 used to train the classifier), but need help assigning coefficients to do such.
I would love a walkthrough on how to use the supplied equation or create my own ASCII matrix files, if that isn't too much to ask.
Thank you!
