Abstract
A recursive algorithm for determining the Gaussian filtered mean surface is presented for measurements of three-dimensional (3-D) engineering surface topography. This algorithm requires a relatively small number of simple mathematical operations such as addition, subtraction, multiplication, or division, so that it has considerable computational efficiency. The zero-phase-filtering technique is used in this algorithm, so there is no phase distortion in the Gaussian filtered mean surface. High-order approximation Gaussian filters are proposed for practical use to assure high accuracy of Gaussian filtering of 3-D surface topography.Proceedings Title
