    Accés restringit per política de l'editorial
    An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows to use them as tele-colorimeters with CIE-XYZ color output, in cd/m2. The spectral characterization ...
  • Diseño de un colorímetro triestímulo a partir de una cámara CCD-RGB 

    Martínez Verdú, Francisco Miguel (Universitat Politècnica de Catalunya, 2001-11-23)
    Tesi
    Accés obert
    Un dispositivo de captura (escáner o cámara) de imágenes digitales no es un instrumento de medida del color como un espectrofotómetro o un tele-espectrocolorímetro. Aunque codifica la información espectral contenida en una ...
  • Evaluación del nivel de repetibilidad para medidas de color obtenidas mediante dos sistemas de captura digital de imagen 

    Chorro, Elisabeth; Vilaseca Ricart, Meritxell; Herrera Ramírez, Jorge Alexis; Perales, Esther; Martínez Verdú, Francisco Miguel; Pujol Ramo, Jaume (2010)

  • Evaluation of the repeatability and reproducibility levels for colour measurement obtained by digital imaging capture devices 

    Chorro, Elisabeth; Vilaseca Ricart, Meritxell; Herrera Ramírez, Jorge Alexis; Perales, Esther; Martínez Verdú, Francisco Miguel; Pujol Ramo, Jaume (2010)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Conventional and multi-spectral digital imaging capture devices can be used for colorimetric measurements. However, a preliminary study of their repeatability and reproducibility is very advisable if they want to be used ...

  • Multispectral system for recovering near-infrared reflectance spectra 

    Arjona Carbonell, Mª Montserrat; Vilaseca Ricart, Meritxell; Pujol Ramo, Jaume; Martínez Verdú, Francisco Miguel (2004)
    Text en actes de congrés
    Accés restringit per decisió de l'autor
    In this paper, we analyze an experimental system for recovering the reflectance spectra of samples in the nearinfrared region of the spectrum (NIR, 800-1000 nm). Recently, CCD cameras with improved response in the NIR ...
