Product Geometry Specification (GPS) Filtering

Part 85.Morphological Region Filter Segmentation

1 Scope

GB/T 26958.85-2022 is the part of the GPS filtration series that deals with morphological areal filters used for segmentation, establishing the terminology and the concepts for dividing a measured areal surface into regions. The document works on the assumption of continuous surfaces. Clause 4 gives the detailed description of the segmentation and clause 5 the general description, covering the watershed algorithm that partitions the surface and the Wolfe pruning algorithm that removes the divisions between regions too slight to be treated as separate features. Informative annexes place the material against the filter matrix model and the GPS matrix model, and add a conceptual diagram. A surface is analysed feature by feature as well as by average height, and any count of features, or any measure of how deep they run, depends entirely on where the boundaries fall: without an agreed segmentation and an agreed pruning rule, two laboratories working from identical measured data report different results, and a texture requirement written on a drawing cannot be verified. Of use to developers of surface metrology software, calibration and surface texture laboratories, and manufacturers who specify areal texture requirements on drawings.

This document establishes terminology and concepts related to morphological segmentation of regions. This document assumes continuous surfaces and specifically describes the watershed

cut algorithm and Wolfe pruning algorithm.
