摘要: Presents a new method for weighted least-squares phase unwrapping. The is full multigrid (FMG) technique that applies Gauss-Seidel relaxation schemes to the partial derivatives of given data on smaller, coarser grids and transfers results finer grids. key idea author's approach maintain in separate arrays correct these at boundaries resulting algorithm up ten times faster than existing algorithms
