cupper oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. the structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. sem images show gradual development of hierarchical structures of copper oxide with different morphology. in order to study the effect of reaction time and te...

the swim-up procedure was used to collect a sperm fraction with improved motility and normal morphology from fertile and infertile semen samples. the untreated and swim-up fractions were analyzed with the hamilton-thorn motility analyser. comparisons were made to see the effect of this sperm selection technique on sperm motility and morphology. they were then examined by transmission electron m...

to evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an iranian population by means of cone beam ct (cbct) images.four hundred cbct images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. vertucci's classification was used to evaluate the number of roots, number of root canals, root leng...

This paper proposes one possibility to generalize the morphological operations particularly, dilation, erosion, opening, and closing to color images. First, properties of a desirable generalization are stated and a brief review is done on former approaches. Then, the method is explained, which is based on a total ordering of the colors in an image induced by its color histogram; this is valid f...

This paper proposes an approach for mathematical morphology operators whose structuring element can locally adapt its orientation across the pixels of the image. The orientation at each pixel is extracted by means of a diffusion process of the average squared gradient field. The resulting vector field, the average squared gradient vector flow, extends the orientation information from the edges ...

We establish in this paper the link between the two main approaches for fuzzy mathematical morphology, based on duality with respect to complementation and on the adjunction property, respectively. We also prove that the corresponding definitions of fuzzy dilation and erosion are the most general ones if a set of classical properties is required. © 2009 Elsevier B.V. All rights reserved.

The concept of strictness of morphological operators is discussed, and it is shown that the ordinary morphological operators have extreme strictness which leads to sensitivity to noise and digital artifacts. Based on this observation new morphological operators that generalize the ordinary morphological operators, are de ned. The generalized operators have controllable strictness and so excessi...

Algorithms are presented which allow to perform morphological transformations on unorganised sets of points represented by their Delaunay triangulation. The results show that these algorithms could behaves as morphological operators such as erosion, dilatation, opening do. As a matter of fact, they actually act as “shape filter”. These algorithms are applied to the problem of scene reconstructi...
