Feature Characterization

This repository contains the companion code for the paper "Feature Characterization for Profile Surface Texture". The algorithm is based on the definitions in ISO 21920-2.

Watershed Segmentation

In the following are some illustrations to show the idea of watershed segmentation. For more information, see the paper.

Usage of feature characterization

The Convention is summarized in the following figure:

The functionality can be tested directly using "minimal_example.m" with or "minimal_example.py" an editable dummy profile. Alternatively, there is a GUI for Matlab "GUI.mlapp" where, for example, the profiles from "data/profiles for case studies" can be loaded and the algorithm applied by varying the various input arguments.
