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 41. This section drafted in accordance with GB/T 1.1-2009 given rules. This section uses the translation method identical with the International Technical Specification ISO /T S16610-41.2006 "Product Geometry Specifications (GPS) filter Wave Part 41. Morphological profile filter disk and horizontal segment filter. " 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.

4 Morphological filter

4.1 Overview The morphology filter described in this section is defined by the Mickowski operation and includes two basic morphological operations (swelling and erosion) And two sub-morphological operations (on and off). Open and close operator also known as morphological filter. Anything that can accomplish Minkovsky and with The technique of poor operation can be used to calculate open and closed morphological filters and corresponding envelope filters. If we study discrete morphological filter, the operation of morphological filter can be greatly simplified, the rest of this section will start Syrian Description. The main body of this section describes the general calculation method. Appendix A and Appendix B describe discrete morphological contour operations and contour filters Specific implementation. The morphology filters that follow this section will have the properties described in 4.3, 4.4, 4.5, 4.6, 5.1, 5.2, 5.3. Note The relationship between morphological contour filters The relationship between circular and horizontal line segments and the filter matrix model is given in Appendix B. 4.2 Discrete representation of input data The sampled contour data is represented by a vector z of size n, which is a discrete representation of the contour. For ease of calculation, it is assumed to be used Isometric sampling separated by Δ. The z element i of z is the estimated value of the input function at iΔ. Example. Given the first five elements of a long input vector, z = [-63.3, -65.0, -67.0, -70.4, -69.6,] in μm and a pitch Δ of 0.5 μm,
