Left ventricle segmentation using a Bayesian approach with distance dependent shape priors
(IOP Publishing, 2020-05-28)
We propose a method for segmentation of the left ventricle in magnetic resonance cardiac images. The framework consists of an initial Bayesian segmentation of the central slice of the volume. This segmentation is used to ...
Continuum theory of gene expression waves during vertebrate segmentation
(IOP Publishing, 2015-09)
The segmentation of the vertebrate body plan during embryonic development is a rhythmic and sequential process governed by genetic oscillations. These genetic oscillations give rise to traveling waves of gene expression ...
Microscope cell color images segmentation by fuzzy morphological reconstruction
(SPIE Digital Library, 2017-01-26)
There are many different methods to perform gray level segmentation in microscope cell images however, in some circumstances, texture features and roughness are not as relevant as the color for the segmentation task. In ...
Segmented poly(esterurethane urea)s from novel urea-diol chain extenders: Synthesis, characterization and in vitro biological properties
(Elsevier, 2008-07)
This work describes the preparation, physicochemical characterization, mechanical properties and in vitro biological properties of two bioresorbable aliphatic segmented poly(esterurethane urea)s (SPEUU) based on ...
A variational shape optimization approach for image segmentation with a Mumford-Shah functional
(Society for Industrial and Applied Mathematics, 2008-12)
We introduce a novel computational method for a Mumford-Shah functional, which decomposes a given image into smooth regions separated by closed curves. Casting this as a shape optimization problem, we develop a gradient ...
The gap gene Krüppel of Rhodnius prolixus is required for segmentation and for repression of the homeotic gene sex comb-reduced
(Academic Press Inc Elsevier Science, 2014-03-01)
The establishment of the anterior–posterior segmentation in insects requires the concerted action of a hierarchical gene network. Here, we study the orthologue of Krüppel gap gene in the hemipteran Rhodnius prolixus (Rp-Kr). ...
The effect of spatial layout on motion segmentation
(Pergamon-Elsevier Science Ltd, 2009-07)
We present a series of experiments exploring the effect of the stimulus spatial configuration on speed discrimination and two different types of segmentation, for random dot patterns. In the first experiment, we find that ...
Percolation of heteronuclear dimers irreversibly deposited on square lattices
(American Physical Society, 2016-09)
The percolation problem of irreversibly deposited heteronuclear dimers on square lattices is studied. A dimer is composed of two segments, and it occupies two adjacent adsorption sites. Each segment can be either a conductive ...
Percolation of defective dimers irreversibly deposited on honeycomb and triangular lattices
(American Physical Society, 2018-11)
The percolation problem of irreversibly deposited dimers on honeycomb and triangular lattices is studied. A dimer is composed of two segments, and occupies two adjacent adsorption sites. Each segment can be either a ...
Assessment of SAR speckle filters in the context of object-based image analysis
