In spite of their limitations, wireless networks are being increasingly used in industrial environments. The electromagnetic phenomena that can occur, along with the interference that may occur due to it being an open ...

[EN] In a fuel injector at the end of the injection, the needle descent and the rapid pressure drop in the nozzle leads to discharge of large, slow-moving liquid structures. This unwanted discharge is often referred as ...

[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 ...

The vibratory behaviour of citrus fruits is studied using slow-motion cameras in order to gain a better understanding of the parameters involved in fruit detachment when mechanical harvesting is done using shakers. Single ...

[EN] On surgery, tools to help vision as X-rays, magnifying glasses, microscopes, stains or endoscopes among others are commonly used. On direct vision, with or without magnification, the application of different illuminants ...

In capsule endoscopy (CE), preparation of the small bowel before the procedure is believed to increase visibility of the mucosa for analysis. However, there is no consensus on the best method of preparation, while comparison ...

A simple technique to avoid color limitations in image capture systems based on chroma key video composition using retroreflective screens and light-emitting diodes (LED) rings is proposed and demonstrated. The combination ...

El principal objetivo de este trabajo, es el desarrollo de una aplicación compilada, mediante la interfaz gráfica de Matlab (GUI), que sea capaz, previo aprendizaje de la aplicación, de localizar la cara en la fotografía, ...

Entre otras aplicaciones, el Grupo de Tratamiento de Señal (GTS) de la Universidad Politécnica de Valencia ha trabajado tradicionalmente en el campo de los ensayos no destructivos por ultrasonidos. el GTS ha desarrollado ...

Along this thesis the actual state of the art algorithms of autonomous text localization and recognition in natural scene images are going to be analyzed, as well as methods for reaching a real-time execution on these ...
