Investigation on the morphological and mineralogical properties of coarse aggregates under VSI crushing operation

International Journal of Pavement Engineering, 2020
In this paper, the role of crushing operation on the cubical controlling features of coarse aggregates, and its influence on the shape distribution characteristics of aggregates (i.e.

Morphological operators on the unit circle

IEEE Transactions on Image Processing, 2001
Images encoding angular information are common in image analysis. Examples include the hue band of color images, or images encoding directional texture information. Applying mathematical morphology to image data distributed on the unit circle is not immediately possible, as the unit circle is not a lattice.

Morphological operators on complex signals

Signal Processing, 2004
This paper presents a novel approach to the generalization of mathematical morphology to complex signals and images. This generalization is strongly dependent upon the issue of multivariate order relationships. Although there is no natural way to order multivariate data such as complex numbers, it is possible to design an order relationship such that ...

A MORPHOLOGICAL OPERATOR FOR CORNER DETECTION

Pattern Recognition, 1998
Abstract This paper presents a new operator for corner detection. This operator uses a variant of the morphological closing operator, which we have called asymmetrical closing. It consists of the successive application of different morphological operators using different structuring elements. Each of these structuring elements used to probe the image

Generalized Fuzzy Morphological Operators

2005
The adjunction in lattice theory is an important technique in lattice-based mathematical morphology and fuzzy logical operators are indispensable implements in fuzzy morphology. This paper introduces a set-valued mapping that is compatible with the infimum in a complete lattice and with a conjunction in fuzzy logic.

Characterization of linear and morphological operators

XII Brazilian Symposium on Computer Graphics and Image Processing (Cat. No.PR00481), 2003
Summary form only given, as follows. In image processing, the transformations of an image to another one are obtained through operators. Among the most important operators are the linear operators and the morphological ones (dilations and erosions). We recall the definition of these operators and present an algebraic characterization of them for the ...

Realisation of morphological operations

IEE Proceedings - Circuits, Devices and Systems, 1995
Multi-input min and max operators are two essential components for dilation and erosion, which are two basic building units for morphological filtering. Many of the more complicated operations of morphological filtering can be decomposed by them. The min or max operator cascades after a bit-serial adder or subtractor is equal to a dilation or erosion ...

Some Morphological Operators in Graph Spaces

2009
We study some basic morphological operators acting on the lattice of all subgraphs of a (non-weighted) graph $\mathbb{G}$. To this end, we consider two dual adjunctions between the edge set and the vertex set of $\mathbb{G}$. This allows us (i) to recover the classical notion of a dilation/erosion of a subset of the vertices of $\mathbb{G}$ and (ii) to

Statistical evaluation of sequential morphological operations

IEEE Transactions on Signal Processing, 1995
In order to properly apply sequential morphological operations to random signals in applications concerned with noise suppression, the authors have examined their statistical properties using different structuring elements. The performance of flat and triangular structuring elements has been evaluated for signals with uniform, Gaussian, and Rayleigh ...
