tps2d
is the core function for Thin Plate Splines. It is used internally for
all TPS graphical functions.tps_apply
is the very same function but with
arguments properly named (I maintain tps2d as it is for historical reasons) when
we want a apply a trasnformation grid.
tps2d(grid0, fr, to)tps_apply(fr, to, new)
a matrix of coordinates on which to calculate deformations
the reference \((x; y)\) coordinates
the target \((x; y)\) coordinates
the target coordinates (again)
a matrix of (x; y)
coordinates with TPS-interpolated
deformations
