44、 space technique conforming to this part of ISO 16610 shall exhibit the characteristics described in 4.2, 4.3, 4.4, 5.1, 5.2, and 5.3.Scale space is a way of decomposing a signal (profile/surface) into objects of different scales. A defining feature of scale space is the property that an object, onc
45、e 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 necessarily be a monotone decreasing function of scale.To define scale space, we need to define the size of objects in a sig
46、nal (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).Note Examples of scale space are given in Annex A. A concept diagram for the concepts for morphological profile filters: sca
47、le 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 technique. In physical terms, sieving involves classifying small solid particles according to a series of sieves with dec
48、reasing 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 different sizes of grains. The contents of each sieve are then either counted or weighed to obtain a histogram of the size
49、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, satisfying the sieve criterion and indexed by a positive number called the 2 ISO 2015 All rights reservedBS EN ISO 16610-49:2015ISO 16610-49:2015(E)scale, could be used to define the concept of size and size distributions, analogous to physically sieving a population of particles as described above.Since size distributions are b
