ActiveGeometrical Product Specifications (GPS) - Filtration - Part 31: Robust profile filters - Gaussian regression filters
产品几何技术规范（GPS） 滤波 第31部分：稳健轮廓滤波器 高斯回归滤波器
Application Summary AI generated
This standard specifies the Gaussian regression filter for robust profile filtration, used to separate roughness and waviness components from surface profiles while suppressing outliers and spikes. It is applied in precision engineering and manufacturing quality control, particularly for measuring surface texture on machined parts with irregular features or contamination. The filter ensures reliable profile evaluation in metrology contexts where conventional filters would distort results due to non-Gaussian data distributions.
