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. ...

Computation of Ramsey Numbers by P Systems with Active Membranes
(World Scientific, 2011)
Ramsey numbers deal with conditions when a combinatorial object necessarily contains some smaller given objects. It is well known that it is very difficult to obtain the values of Ramsey numbers. In this work, a theoretical ...

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 ...

Recognizer P Systems with Antimatter
(Romanian Academy, Section for Information Science and Technology, 2015)
In this paper, we consider recognizer P systems with antimatter and the in uence of the matter/antimatter annihilation rules having weak priority over all the other rules or not. We rst provide a uniform family of ...

Computing Homology Groups in Binary 2D Imagery by Tissue-like P Systems
(Romanian Academy, Section for Information Science and Technology, 2010)
We present a new solution for the Homology Groups of Binary 2D Image (HGB2I) Problem by using Membrane Computing techniques. This is a classical problem in Homology Theory which tries to calculate the number of connected ...

Efficient simulation of tissue-like P systems by transition cell-like P systems
(Springer, 2009)
In the framework of P systems, it is known that the construction of exponential number of objects in polynomial time is not enough to efficiently solve NP-complete problems. Nonetheless, it could be sufficient to create ...
