In this work, an approach to the problem of impulsive noise removal in gray scale images is presented. We describe two models of adaptive mathematical morphology that improve the classical mathematical morphology in the removal of impulsive noise. The proposed method adjust the structuring elements to the local context of the image. The comparison with classical mathematical morphology denoisin...

background: a method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. materials and methods: the method was based on the following idea: (i) before treatment, a series of fluoroscopic images corresponding to different bre...

What the algebra of convolution does for linear systems, the algebra of mathematical morphology does for shape. Since shape is a prime carrier of information in machine vision, there should be little surprise about the importance of the mathematical morphology. Now adays the operations of mathematical morphology are very much useful in object or defect identification required in industrial visi...

One of the extensions of binary morphology to greyscale images is given by the classical fuzzy mathematical morphology. Interval-valued fuzzy mathematical morphology further extends the latter theory by now also allowing uncertainty in the grey values of the image. In this paper, the decomposition of the intervalvalued fuzzy morphological operations into their binary counterparts is studied bot...

Morphonotactic consonant clusters originate through morphological operations and are mostly combinations of consonants across morpheme boundaries. As they are processed faster and acquired earlier than phonotactic clusters, it is hypothesised that in speech production, morphonotactic clusters are more robust and highlighted than phonotactic clusters. The present study pursues two goals: it exam...

In this article we introduce mathematical morphology on hypergraphs. We first define lattice structures and then mathematical morphology operators on hypergraphs. We show some relations between these operators and the hypergraph structure, considering in particular duality and similarity aspects.

This paper proposes a general framework for the semantics of honorific expressions, including honorific pronouns, morphology, and discourse particles. Such expressions are claimed to indicate a level of politeness which must be compatible with a level of formality fixed by the discourse context together with sociolinguistic factors, and, with their use, to change the range of formality the cont...
