Multithresholding techniques in SAR image classification
(Elsevier Science, 2021-08)
Beyond bilevel segmentation, multithresholding (MT) is a powerful technique that is seldom considered in image analysis. In active imaging techniques, however, MT appears as a significant alternative due to its obliviousness ...
Intuitionistic fuzzy set and fuzzy mathematical morphology applied to color leukocytes segmentation
(Springer, 2019-10-25)
This work presents a new algorithm based on Atanassov’s intuitionistic fuzzy sets and fuzzy mathematical morphology to leukocytes segmentation in color images. The main idea is based on modeling a color image as an Atanassov’s ...
Diphenylanthrylene and diphenylfluorene-based segmented conjugated polymer films as fluorescent chemosensors for nitroaromatics in aqueous solution
(Elsevier Science Sa, 2014-11)
A new regularly segmented conjugated polymer with diphenylanthryl chromophores bearing oxyethylene side chains was synthesized. The amorphous polymer was solution-processable. The formation of aggregated species in solid ...
Lumen-intima and media-adventitia segmentation in IVUS images using supervised classifications of arterial layers and morphological structures
(Elsevier, 2019-08)
Background: Intravascular ultrasound (IVUS) provides axial grey-scale images of blood vessels. The large number of images require automatic analysis, specifically to identify the lumen and outer vessel wall. However, the ...
Site-bond percolation of heteronuclear dimers irreversibly deposited on square lattices
(American Physical Society, 2017-12)
A generalization of the site-bond percolation problem was studied, in which pairs of neighboring sites (site dimers) and bonds are occupied irreversibly, randomly, and independently on homogeneous square surfaces. A dimer ...
Chemosensing of nitroaromatics with a new segmented conjugated quaterphenylene polymer
(Pergamon-Elsevier Science Ltd, 2011)
Effect of light and protein phosphorylation on photoreceptor rod outer segment acyltransferase activity
(Elsevier Science Inc, 2002-07-01)
Rod outer segments (ROS) exhibit high acyltransferase (AT) activity, the preferred substrate of which being lysophosphatidylcholine. To study factors possibly regulating ROS AT activity purified ROS membranes were assayed ...
Embedded wireless delay tolerant networks on chips for segmented architectures
(Inderscience Publishers, 2022-02)
Fault-tolerant systems were traditionally based on the use of local redundancies. But currently, network technologies have allowed the emergence of novel distributed alternatives. Among these, disruption tolerant networks ...
The Endocannabinoid System Is Present in Rod Outer Segments from Retina and Is Modulated by Light
(Springer, 2019-04-24)
The aim of the present research was to evaluate if the endocannabinoid system (enzymes and receptors) could bemodulated by light in rod outer segment (ROS) from bovine retina. First, we analyzed endocannabinoid ...
Automatic design of aperture filters using neural networks applied to ocular image segmentation
(European Association for Signal Processing, 2014-09)
Aperture filters are image operators which combine mathematical morphology and pattern recognition theory to design windowed classifiers. Previous works propose designing and representing such operators using large decision ...
