    • Infrared imaging software for jet fire analysis 

      Mata Miquel, Cristian; Pastor Ferrer, Elsa; Rengel Darnaculleta, Francisco de Borja; Valero Pérez, Mario Miguel; Planas Cuchi, Eulàlia; Palacios, Adriana; Casal Fàbrega, Joaquim (2018)
      Conference report
      Open Access
      Jet fires, often originated by the ignition of hydrocarbon sonic jets, are characterized by a high momentum jet flame lifted from the outlet orifice. The high thermal flux released, especially if there is flames impingement ...
    • Multispectral and colour imaging systems for the detection of small vertebrate fossils: A preliminary study 

      Delpueyo Español, Xana; Vilaseca Ricart, Meritxell; Furió, Marc; Burgos Fernández, Francisco Javier; Pujol Ramo, Jaume (2016)

    • Optical validation of combined images for high-secure identification. ID tags and processors 

      Millán Garcia-Varela, M. Sagrario; Pérez Cabré, Elisabet; Bahram, Javidi (2007)
      Conference report
      Restricted access - publisher's policy
      In this work, we use a novel multifactor encryption-authentication technique that reinforces optical security by allowing the simultaneous AND-verification of more than one primary image. This optical technique is attractive ...
    • OUFTI-NEXT : study of refractive lenses for an infrared camera 

      Riera Salvà, Anna (Universitat Politècnica de Catalunya, 2019-05-22)
      Master thesis
      Open Access
      Covenantee:   Université de Liège / Centre Spatial de Liège
      The aim of this master thesis is to survey the capability of a refractive design to accommodate the requirements of the OUFTI-NEXT payload. The optical design for thermal infrared camera is challenging:• the lack of glass ...
    • Texture evaluation of automotive coatings by means of a gonio-hyperspectral imaging system based on light-emitting diodes 

      Burgos Fernández, Francisco Javier; Pujol Ramo, Jaume; Perales Romero, Esther; Martínez Verdú, Francisco Miguel; Vilaseca Ricart, Meritxell (Multidisciplinary Digital Publishing Institute (MDPI), 2020-03-27)
      Article
      Open Access
      Sparkle and graininess are textural effects that appear as intrinsic spatial features of coatings containing goniochromatic pigments, whereas others such as mottling are undesired outcomes. In this study, we present new ...
    • Thermal anomalies detection in the infrarred Spectrum at Weldestein 7-X 

      Moreno Punzano, Alex (Universitat Politècnica de Catalunya, 2020-02-05)
      Bachelor thesis
      Open Access
      In 2018, a series of experiments were made on the nuclear fusion reactor Weldenstein 7-X. Throughout these experiments, a huge amount of information was generated and gathered. The aim of this work is use image processing ...
