4. The system of claim 1 , the interpolation component interpolates the original trajectory to a two-dimensional grid and performs a “rubber sheet” displacement technique to warp the handwriting.
4. The system of claim 1 , the interpolation component interpolates the original trajectory to a two-dimensional grid and performs a “rubber sheet” displacement technique to warp the handwriting. 5. The system of claim 4 , the displacement component performs a “rubber rod” displacement technique on the interpolated trajectory, which enforces rigidity constraints on the interpolated trajectory after application of the rubber sheet displacement technique resulting in a normalized handwriting.
