Geometrical product specifications (GPS) - Filtration - Part 45: Morphological profile filters: Segmentation (ISO 16610-45:2025)
This part of ISO 16610 develops the terminology and concepts for Profile morphological segmentation. In particular it describes the watershed segmentation method, the Wolf pruning method and the Crossing-the-Line Method. This document assumes a continuous surface.
Geometrische Produktspezifikation (GPS) - Filterung - Teil 45: Morphologische Profilfilter: Segmentierung (ISO 16610-45:2025)
Dieses Dokument entwickelt die Terminologie und die Konzepte der profilhaften morphologischen Segmentierung. Es beschreibt insbesondere das Wasserscheiden-Segmentierungsverfahren, das Wolf-Beschneidungsverfahren und das Liniendurchgangsverfahren. Dieses Dokument beruht auf der Annahme einer durchgängigen Oberfläche.
Spécification géométrique des produits (GPS) - Filtrage - Partie 45: Titre manque (ISO 16610-45:2025)
Le présent document définit la terminologie et développe les concepts applicables à la segmentation morphologique de profils. Il spécifie en particulier la méthode de segmentation par ligne de partage des eaux, la méthode d’élagage de Wolf et la méthode de franchissement de ligne. Le présent document suppose une surface continue.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that

Introduction
This document is a geometrical product specification (GPS) standard and is to be regarded as a general GPS
standard (see ISO 14638). It influences chain links C and E in the GPS matrix structure.
The ISO GPS matrix model given in ISO 14638 gives an overview of the ISO GPS system of which this
document is a part. The fundamental rules of ISO GPS given in ISO 8015 apply to this document and the
default decision rules given in ISO 14253-
