Module lbv 

Laplacian Boundary Value (LBV) background field removal

LBV removes background fields by solving the Laplace equation inside the mask with Dirichlet boundary conditions from the total field at the mask boundary.

The method exploits that background fields satisfy ∇²b = 0 inside the ROI.
