Fully automatized parallel segmentation of the optic disc in retinal fundus images
(Elsevier, 2016-11)
This paper presents a fully automatic parallel software for the localization of the optic disc (OD) in retinal fundus color images. A new method has been implemented with the Graphics Processing Units (GPU) technology. ...

Descriptional Complexity of Tissue-Like P Systems with Cell Division
(Springer, 2009)
In this paper we address the problem of describing the complexity of the evolution of a tissue-like P system with cell division. In the computations of such systems the number of (parallel) steps is not sufficient to ...

Skeletonizing Images by Using Spiking Neural P Systems
(Fénix Editora, 2012)
Skeletonizing an image is representing a shape with a small amount of information by converting the initial image into a more compact representation and keeping the meaning features. In this paper we use spiking neural ...

A Characterization of PSPACE with Antimatter and Membrane Creation
(Fénix Editora, 2015)
The use of negative information provides a new tool for exploring the limits of P systems as computational devices. In this paper we prove that the combination of antimatter and annihilation rules (based on the annihilation ...

A uniform family of tissue P systems with cell division solving 3-COL in a linear time
(Elsevier, 2008)
Several examples of the efficiency of cell-like P systems regarding the solution of NPcomplete problems in polynomial time can be found in the literature(obviously, trading space for time). Recently, different new models ...

Computational efficiency of dissolution rules in membrane systems
(Taylor and Francis, 2006)
Trading (in polynomial time) space for time in the framework of membrane systems is not sufficient to efficiently solve computationally hard problems. On the one hand, an exponential number of objects generated in ...

Operadores de generalización para el aprendizaje clausal
(2002)
"En esta memoria hemos estudiado los procesos de generalización, el paso de lo particular a lo general, cuando la información está expresada en lenguaje clausal. Para ello hemos definido unos operadores adaptados a los ...

Graphical Modeling of Higher Plants Using P Systems
(Springer, 2006)
L systems have been widely used to model and graphically represent the growth of higher plants [20]. In this paper we continue developing the framework introduced in [21], which make use of the topology of membrane ...

Segmenting images with gradient-based edge detection using Membrane Computing
(Elsevier, 2013)
In this paper, we present a parallel implementation of a new algorithm for segmenting images with gradient-based edge detection by using techniques from Natural Computing. This bio-inspired parallel algorithm has been ...
