Expand description

Laplacian phase unwrapping

Uses FFT-based Poisson solver with periodic boundary conditions. Fast and robust but may have issues at mask boundaries.

§Arguments

  • phase - Wrapped phase (nx * ny * nz)
  • mask - Binary mask (nx * ny * nz), 1 = inside ROI
  • nx, ny, nz - Array dimensions
  • vsx, vsy, vsz - Voxel sizes in mm

§Returns

Unwrapped phase
