The fundamental rules of ISO/GPS given in I

34、ifies the metrological characteristics of robust areal Gaussian regression filters, for the rotationally symmetric filtration of nominal planar surfaces and the filtration of nominal cylindrical surfaces.The filter is insensitive against specific phenomena in the input data (e.g. spike discontinuiti

35、es as well as deep valleys and high peaks, etc.).
