When plane-wave destruction (PWD) is implemented by implicit finite differences, the local slope estimated an iterative algorithm. We propose analytical estimator of that based on convergence analysis Using estimator, we design a noniterative method to estimate slopes three-point PWD filter. Compared with estimation, proposed needs only one regularization step, which reduces computation time significantly. With directional decoupling filter, algorithm also applicable 3D estimation. present synthetic and field experiments demonstrate can yield correct estimation result shorter computational time.
