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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

This edition of ISO 16610-31 cancels and replaces ISO 16610-31:2016, which has been technically
revised.
The main changes are as follows:
— This document defines ideal continuous Gaussian regression filters for open profiles and for closed
profiles, exemplary applied to roundness profiles.
— A normative iterative solution for the ideal continuous Gaussian regression filter is given.

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 link C of all chains of standards.
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 14253-1 apply to the specifications made in accordance with this
document, unless otherwise indicated.
For more information on the relationship of this document to filtration matrix model, see Annex C.
For more detailed information of the relation of this document to other standards and the GPS matrix
model, see Annex D.
This document develops the terminology and a concept of robust Gaussian regression filters for profiles.
It separates the large and small lateral scale components of a surface profile in such a way that the
surface profile can be reconstructed without altering. The robust Gaussian regression filter for profiles
reduces the influence of protruding dales and hills.

Part 31:
Robust profile filters: Gaussian regression filters
1 Scope
This document specifies robust Gaussian regression filters for the filtration of surface profiles. It
defines, in particular, how to separate large and small lateral scale components of a surface profile with
protruding dales and hills.
The concepts presented for closed profiles are applicable to the case of roundness filtering. Where
appropriate, these concepts can be extended to generalized closed profiles, especially for profiles with
re-entrant features.
