On a Tentative Method of Smoothing of Contour Height by the Finite-difference Smoothing Operators

[摘要]  In order to filter out small scale disturbances in the contour field, a tentative method of smoothing is proposed. This method is specified by the finite-difference smoothing operators combined with two sorts of single smoothing operators. Only by one or two times iterations of this combined finite-difference operator, the small scale disturbances are filtered out almost completely, and at the same time, the large scale ones are retained essentially unchanged.
