El concepto de métrica fuzzy a través del filtrado de imágenes digitales

Camarena, Joan-Gerard; Gregori, Valentín; Morillas, Samuel; Sapena, Almanzor (Universitat Politècnica de València, 2013-06-02)

[EN] Fuzzy logic has been recently successfully used in several Engineering applications. In particular, fuzzy metrics have been applied to color image filtering improving, in many cases, classical filters results. In this ...
Fuzzy averaging filter for impulse noise reduction in colour images with a correction step

Gregori Gregori, Valentín; Morillas, Samuel; Roig, Bernardino; Sapena Piera, Almanzor (Elsevier, 2018)

[EN] In this paper we propose a fuzzy detection and reduction method for impulse noise in colour images. Detection is based on the fuzzyfication of a well-known statistic called ROD. The noise degrees obtained are used to ...
Localised rank-ordered differences vector filter for suppression of high-density impulse noise in colour images

Roig, Bernardino; Estruch, Vicente-Domingo (Institution of Engineering and Technology (IET), 2016-01)

This research presents a complete study of a new alternating vector filter for the removal of impulsive noise in colour images. The method is based on an impulsive noise detector for greyscale images that has been adapted ...
On the importance of metrics in practical applications

Camarena, Joan-Gerard; Morillas, Samuel; Cisneros, F.J. (Universitat Politècnica de València, 2011-06-05)

[EN] Students motivation for learning mathematical concepts can be increased when showing the usefulness of these concepts in practical problems. One important mathematical concept is the concept of metric space and, more ...
Performance of a 60-GHz DCM-OFDM and BPSK-Impulse ultra-wideband system with radio-over-fiber and wireless transmission employing a directly-modulated VCSEL

Beltrán, Marta; Jensen, Jesper Bevensee; Yu, Xianbin; Llorente, Roberto; Rodes, Roberto; Ortsiefer, Markus; Neumeyr, Christian; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)

[EN] The performance of radio-over-fiber optical transmission employing vertical-cavity surface-emitting lasers (VCSELs), and further wireless transmission, of the two major ultra-wideband (UWB) implementations is reported ...
