标准摘要
[中文适用范围]： 本文件规定了用于表面轮廓过滤的稳健高斯回归滤波方法。特别是，它定义了如何将具有突出沟槽和山脊的表面轮廓的长程和短程横向成分分离。针对封闭轮廓所提出的概念可适用于圆度滤波的情况。在适当的情况下，这些概念还可以扩展到广义的封闭轮廓，特别是具有凹陷特征的表面轮廓。 [外文原描述]： This document specifies robust Gaussian regression filters for the filtration of surface profiles. It defines, in particular, how to separate large- and small-scale lateral components of surface profiles with protruding dales and hills. The concept presented for closed profiles are applicable to the case of roundness filtering. Where appropriate, these concept can be extended to generalized closed profiles, especially for surface profiles with re-entrant features.
