ISO 16610-61:2015规定了用于标称平面旋转对称过滤和标称圆柱表面过滤的线性面积高斯滤波器。它特别指定了如何分离曲面的长波和短波分量。
ISO 16610-61:2015 specifies linear areal Gaussian filters for the rotationally symmetric filtration of nominal planar surfaces and the filtration of nominal cylindrical surfaces. It specifies, in particular, how to separate long and short wave components of a surface.
