Smoothing Problem in 2D Images with Tissue-like P Systems and Parallel Implementation
(Fénix Editora, 2011)
Smoothing is often used in Digital Imagery to reduce noise within an image. In this paper we present a Membrane Computing algorithm for smoothing 2D images in the framework of tissue-like P systems. The algorithm has ...

Solving the 3-COL Problem by Using Tissue P Systems without Environment and Proteins on Cells
(Fénix, 2016)
The 3-COL problem consists on deciding if the regions of a map can be coloured with only three colors bearing in mind that two adjacent regions must be coloured with di erent colors. It is a NP problem and it has been ...

Searching Partially Bounded Regions with P Systems
(Springer, 2014)
The problem of automatically marking the interior and exterior regions of a simple curve in a digital image becomes a hard task due to the noise and the intrinsic difficulties of the media where the image is taken. In this ...

Thresholding 2D Images with Cell-like P Systems
(Romanian Academy, 2010)
Thresholding is the process of splitting a digital image into sets of pixels in order to make it easier to analyze. Pixels are ordered according to a scale of one of their features as brightness or color and the ¯nal ...

Tissue-like P Systems Without Environment
(Fénix Editora, 2010)
In this paper we present a tissue-like P systems model with cell division the environment has been replaced by an extra cell. In such model, we present a uniform family of recognizer P systems which solves the Subset Sum ...

Solving the Bin-Packing Problem by Means of Tissue P System with 2-Division
(Springer, 2017)
The ability of tissue P systems with 2-division for solving NP problems in polynomial time is well-known and many solutions can be found in the literature to several of such problems. Nonetheless, there are very few ...

Array Tissue-like P Systems
(Fénix Editora, 2010)
Array grammars have been studied in the framework of Membrane Comput- ing by using rewriting rules from transition P systems. In this paper we present a new approach to dealing with array grammars by using tissue-like P ...

Solving the 3-COL problem by using tissue P systems without environment and proteins on cells
(ELSEVIER SCIENCE INC, 2018)
The 3-COL problem consists on deciding if the regions of a map can be coloured with only three colors bearing in mind that two adjacent regions must be coloured with different colors. It is a NP problem and it has been ...
