Variations of the regularization method involve demodulating certain points in the low frequency region of the fringe pattern. This point can then be used to seed the estimated phase field. The algorithm then follows a somewhat analogously to crystal growing. | Variations of the regularization method involve demodulating certain points in the low frequency region of the fringe pattern.
