backgrounds: genus trichostrongylus (nematoda: trichostrongylidae) is one of the most impor­tant zoonotic nematodes with wide geographic distribution in the world. the purpose of the present study was to describe morphological and morphometrical characteristics of male trichostrongylus species, currently prevalent in domestic ruminants of khuzestan province , south­west iran. methods: gastro-in...

We describe our partially completed work on a set of morphological algorithms for recognizing handwritten numerals. The basic morphological operations { dilation, erosion, opening and closing { are used to extract characteristic features of these characters and check for their appropriate topological con guration. The paper describes the key shape characterization for two groups containing a to...

In contrast to the widely used mean-line based evaluation techniques, the capabilities of morphological methods are not fully recognized in practice. Morphological operations, e.g. dilation, erosion, closing and opening, are useful tools in surface metrology and dimensional metrology. This paper presents a variety of novel applications of morphological operations in association with several of ...

Morphological operations are simple mathematical constructs, which have led to effective solution for many problems in image processing and computer vision. These solutions employ discrete operators and are applied to digitized images. The mathematics behind the morphological operators also exists in the continuous domain, the domain where the images came from. We observed that the discrete ope...

This paper presents a new application of mathematical morphology (MM) operators for low speed slew bearing condition monitoring. The MM operators were used as a signal processing step and feature extraction method for bearing vibration signals. Four basic MM operators; erosion, dilation, closing and opening, were studied. This paper also investigates another potential MM operator, namely gradie...
