Scope
GB/Z 26958.49-2011 is the English-translated version of 产品几何技术规范（GPS） 滤波 第49部分：形态学轮廓滤波器 尺度空间技术.
GB/Z 26958.49-2011 is Part 49 of the GB/Z 26958 series of guiding technical documents on filtration within geometrical product specifications, and it deals with morphological scale space techniques for surface profiles.
It is a translated identical adoption of ISO/TS 16610-49:2006, with the international text recast as a Chinese guiding document rather than a mandatory standard.
The document sets out the basic vocabulary of these techniques and how they are used: size distribution as an indexable set of opening operations that meets the sieve criterion, anti-size distribution as the corresponding set of closing operations, opening defined as erosion followed by dilation, closing as dilation followed by erosion, and the sieve criterion itself as a nesting rule on the basic mappings.
It builds on Part 1 and Part 40 of the same series. It was issued on 19 July 2011.

Foreword
GB /Z 26958 "Geometrical Product Specifications (GPS) filtering" national standardization of technical guidance document is divided into 89, has been transformed For the national standardization of technical documents have the following 9 parts.
--- Part 1. Overview and basic concepts;
--- Part 20. Basic concepts of linear contour filters;
--- Part 22. Linear contour filter spline filter;
--- Part 29. Linear contour filter spline wavelet;
--- Part 31. Robust contour filter Gaussian regression filter;
--- Part 32. Robust contour filter spline filter;
--- Part 40. Morphological contour filter basic concepts;
--- Part 41. Morphology contour filter disk and horizontal line segment filter;
--- Part 49. Morphology contour filter scale space technology.
This section GB /Z 26958 Part 49.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This section uses the translation method is equivalent to using the international technical standard ISO /T S16610-49.2006 "Product Geometrical Specifications (GPS) filter Wave Part 49. Morphological contour filter scale space technology ".
For ease of use, this section made the following editorial changes.
--- "This part of International Technical Specifications" be replaced by "This part of the guidance of technical documents";
--- Removed the foreword and foreword of international technical specification;
--- In technical content and preparation of the format in line with the international technical specifications.

3 Terms and definitions
GB /Z 26958.1-2011, GB /Z 26958.40-2011 defined and the following terms and definitions apply to this document.
3.1 Size distributions
An indexable set of open operations that satisfy the filter criteria.
3.1.1 Opening operation
Morphological Filter Morphology Operation after Corrosion and Expansion.
Note Open operation is both a morphological filter and one of the two foundational building blocks that form other morphological filters.
3.2 Anti-size distribution
An indexable set of closed operations that satisfy the filter criteria.
3.2.1 Closed operation closing
Morphology Filter Morphology Operation after Expansion and Corrosion.
Note Closed operation is both a morphological filter and one of the two foundational building blocks that form other morphological filters.
3.3 Screening criteria
The application of two basic mappings to a part of the surface in succession is exactly the same as applying only one of the basic mappings, that is, the basic mapping has the highest Nested index guidelines.
Note: The following math terms are used for mapping.
