چکیده

If a random set (binary image) is composed of randomly sized, disjoint translates arising as homothetics of a ®nite number of compact primitives and a granulometry is generated by a convex, compact set, then the granulometric moments of the random set can be expressed in terms of model parameters. This paper shows that, under mild conditions , any ®nite vector of granulometric moments possesses a multivariate distribution that is asymptotically normal. Since Gaussian maximum-likelihood classi®cation is often used when employing the granulometric moments for texture classi®cation, the asymptotic joint normality of the moments gives support to the good results thereby obtained .

Optimal linear granulometric estimation for random sets

This paper addresses two pattern-recognition problems in the context of random sets. For the .rst, the random set law is known and the task is to estimate the observed pattern from a feature set calculated from the observation. For the second, the law is unknown and we wish to estimate the parameters of the law. Estimation is accomplished by an optimal linear system whose inputs are features ba...

Non-homothetic granulometric mixing theory with application to blood cell counting

A granulometry is a family of morphological openings by scaled structuring elements. As the scale increases, increasing image area is removed. Normalizing removed area by the total area yields the pattern spectrum of the image. The pattern spectrum is a probability distribution function and its moments are known as granulometric moments. Modeling the image as a random set, the pattern spectrum ...

On the Asymptotic Statistics of the Number of Occurrences of Multiple Permutation Patterns

We study statistical properties of the random variables Xσ(π), the number of occurrences of the pattern σ in the permutation π. We present two contrasting approaches to this problem: traditional probability theory and the “less traditional” computational approach. Through the perspective of the first one, we prove that for any pair of patterns σ and τ , the random variables Xσ and Xτ are jointl...

Asymptotic Normality Through Factorial Cumulants and Partition Identities

In the paper we develop an approach to asymptotic normality through factorial cumulants. Factorial cumulants arise in the same manner from factorial moments as do (ordinary) cumulants from (ordinary) moments. Another tool we exploit is a new identity for 'moments' of partitions of numbers. The general limiting result is then used to (re-)derive asymptotic normality for several models including ...

Heterogeneous morphological granulometries

The most basic class of binary granulometries is composed of unions of openings by structuring elements that are homogeneously scaled by a single parameter. These univariate granulometries have previously been extended to multivariate granulometries in which each structuring element is scaled by an individual parameter. This paper introduces the more general class of "lters in which each struct...
