Characterization of a digital camera as an absolute triestimulus colorimeter
Martínez Verdú, Francisco Miguel; Pujol Ramo, Jaume; Vilaseca Ricart, Meritxell; Capilla, Pascual (2004)
Conference report
Restricted access - publisher's policyAn 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)
Doctoral thesis
Open AccessUn 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 ... -

Multispectral system for recovering near-infrared reflectance spectra
Arjona Carbonell, Mª Montserrat; Vilaseca Ricart, Meritxell; Pujol Ramo, Jaume; Martínez Verdú, Francisco Miguel (2004)
Conference report
Restricted access - author's decisionIn 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 ... -

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 AccessSparkle 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 ... -
