28、 ISO 16610 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain links 3 and 5 in the GPS matrix structure.The ISO/GPS Masterplan given in ISO 14638 gives an overview of the ISO/GPS system of which this part of I

29、SO 16610 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 16610 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this part of ISO 16610, unless otherwise indicated.For more detailed information of the relation

30、about this part of ISO 16610 to the GPS matrix model, see Annex D.This part of ISO 16610 develops the terminology and concepts for morphological scale space techniques.EN ISO 16610-49:2015 (E) 5DIN EN ISO 16610-49:2015-12 1 ScopeThis part of ISO 16610 specifies morphological scale space techniques.

41、(profile/surface) into objects of different scales. A defining feature of scale space is the property that an object, once present at some scale in a signal, shall persist all the way through scale space to zero scale. This is often called the monotone property, since the number of objects shall nec

42、essarily be a monotone decreasing function of scale.To define scale space, we need to define the size of objects in a signal (profile/surface). The concept of the size and anti-size distribution is a mathematical generic approach to the definition of size of objects in a signal (profile/surface).Not

43、e Examples of scale space are given in Annex A. A concept diagram for the concepts for morphological profile filters: scale space techniques is given in Annex B. The relationship to the filtration matrix model is given in Annex C.4.2 Size and anti-size distributionsSieving is a commonly used sizing

44、technique. In physical terms, sieving involves classifying small solid particles according to a series of sieves with decreasing mesh openings. In the first place, the population of different sized grains are allowed to work their way through the sieves (a transformation) in order to classify the di

45、fferent sizes of grains. The contents of each sieve are then either counted or weighed to obtain a histogram of the size distribution of the original population of particles.Matheron4was the first to define mathematically the concept of size. He demonstrated that a family of morphological openings,

46、satisfying the sieve criterion and indexed by a positive number called the EN ISO 16610-49:2015 (E) 7DIN EN ISO 16610-49:2015-12 N3)National footnote: SOURCE: ISO 16610-1:2015, 3.4.1. N3)scale, could be used to define the concept of size and size distributions, analogous to physically sieving a popu

47、lation of particles as described above.Since size distributions are based on a family of opening filters, the size distribution measures the width of peaks on the signal/image. Using the opening filter of a particular scale eliminates peaks whose widths are less than this given scale (see Figure 1).

48、 The dual concept of anti-size distributions based on a family of closing filters measures the width of valleys on the signal/image. Using the closing filter of a particular scale eliminates valleys whose widths are less than this given scale (see Figure 1).KeyA original profileB profile after closi
