Plot (a) of displacement error (DE) values measured by our grid‐based method versus true DE values for various magnitudes of B‐spline warping. Either 500, 1000, 3000, or 5000 randomly located grid points were used. The solid dark line depicts correct measurement of true values. Similar plot (b) for axial components of DE.
