A model based on local graphs for colour images and its application for Gaussian noise smoothing

Pérez-Benito, Cristina; Morillas, Samuel; Jordan-Lluch, Cristina; Conejero, J. Alberto (Elsevier, 2018)

[EN] In this paper, a new model for processing colour images is presented. A graph is built for each image pixel taking into account some constraints on links. Each pixel is characterized depending on the features of its ...
A new approach to occupancy map modeling in navigation assisted by computer vision

Riquelme Madrona, Julio; Ortigosa, Nuria; Magal Royo, Teresa; Morillas, Samuel; Peris Fajarnes, Guillermo (2011)

A note on convergence in fuzzy metric spaces

Gregori Gregori, Valentín; Miñana, Juan-José; Morillas, Samuel (University of Sistan and Baluchestan, 2014-08)

[EN] The sequential p-convergence in a fuzzy metric space, in the sense of George and Veeramani, was introduced by D. Mihet as a weaker concept than convergence. Here we introduce a stronger concept called s-convergence, ...
A note on local bases and convergence in fuzzy metric spaces

Gregori Gregori, Valentín; Miñana Prats, Juan José; Morillas Gómez, Samuel (Elsevier, 2014-02-15)

In the context of fuzzy metrics in the sense of George and Veeramani, we study when certain families of open balls centered at a point are local bases at this point. This question is related to p-convergence and ...
A procedure for detection of border communities using convolution techniques

Montañana, José Miguel; Hervás , Antonio; Morillas, Samuel; Soriano Jiménez, Pedro Pablo (Universitat Politècnica de València, 2021-11-30)

[EN] Many complex systems can be modeled by graphs and networks, [4]. In some problems, the study of communities allows quantitative and qualitative approaches and obtaining some knowledge about the structure of the graph ...
A simple fuzzy method to remove mixed Gaussian-Impulsive noise from color images

Camarena Estruch, Joan Gerard; Gregori Gregori, Valentín; Morillas, Samuel; Sapena Piera, Almanzor (Institute of Electrical and Electronics Engineers (IEEE), 2013-10-02)

Mixed impulsive and Gaussian noise reduction from digital color images is a challenging task because it is necessary to appropriately process both types of noise that in turn need to be distinguished from the original image ...
Adaptive marginal median filter for colour images

Morillas, Samuel; Gregori Gregori, Valentín; Sapena Piera, Almanzor (MDPI, 2011)

[EN] This paper describes a new filter for impulse noise reduction in colour images which is aimed at improving the noise reduction capability of the classical vector median filter. The filter is inspired by the application ...
Algoritmos de detección de comunidades en grafos y aplicación en conjuntos de datos de tránsito en aeropuertos y trasvase de alumnos entre titulaciones de la UPV

Méndez Carmona, Alejandro (Universitat Politècnica de València, 2022-09-08)

[CA] Els avanços en teoria de grafs i anàlisi de xarxes complexes han estat fonamentals per a una millor comprensió dels sistemes complexos que poden aparèixer a la vida real. L’estructura comunitària és una de les ...
Application of image registration methods to gammagraphy explorations with meta- iodobenzylguanidine for the treatment of neuroblastoma

Muñoz Pérez, Álvaro (Universitat Politècnica de València, 2012-10-29)

Neuroblastoma is a childhood cancer with a high mortality. To detect it, a gammagraphy scan is done, injecting prior to it a radioactive isotope, the iodobenzylguanidine (MIBG), to the patient. MIBG reacts with the cancer, ...
Application of probabilistic modeling to predict road pavement deterioration

Viana Llovell, Sergio (Universitat Politècnica de València, 2024-10-22)

[EN] An important problem in the Civil Engineering field concerns the maintenance of pavement in the transportation network. Pavement deterioration can be measured in diverse ways, being one of them the so-called ...
