Langues : Anglais (eng) Index. décimale : 535.6 Couleur Résumé : Film restoration is a complex and multidisciplinary field that requires the collaboration of many professionals. Here, we present a series of ongoing unresolved problems, focusing on digitisation, digital restoration and conservation. Note de contenu : - Digitisation - Digital restoration - Conservation - Fig. 1 : A graphical representation of the film restoration workflow - Fig. 2 : An example of the original frame extracted from the original video "Fiat 508" (193X) and the restored digital copy. It is possible to notice that the video steady produced a cut (ie information loss) at the edges of the frames - Fig. 3 : An example of the original frame extracted from the original video "La strage di Piazza della Loggia: i funerali" (Brescia, 1974), the copy restored manually through video-editing software, and the copy restored through the automatic colour equalisation (ACE) algorithm DOI : 10.1111/cote.12488 En ligne : https://onlinelibrary.wiley.com/doi/epdf/10.1111/cote.12488 Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=35593 [article]

The limits of colorimetry in cultural heritage applications / Alice Plutino in COLORATION TECHNOLOGY, Vol. 137, N° 1 (02/2021)  

[article]  inCOLORATION TECHNOLOGY > Vol. 137, N° 1 (02/2021) . - p. 56-63 Titre : The limits of colorimetry in cultural heritage applications Type de document : texte imprimé Auteurs : Alice Plutino, Auteur ; Gabriele Simone, Auteur Année de publication : 2021 Article en page(s) : p. 56-63 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 535.6 Couleur Résumé : Colours in cultural heritage are not only means of expression, but also materials with physical and chemical properties. Since the beginning of the current century, colorimetry has become a fundamental field aiming at restoring, preserving and valorising the art works. There are different colorimetric applications in cultural heritage (eg, from light design to digitisation and modelling), and the variety of cultural material is extremely wide, from statues and frescoes, to old book and films. In this heterogeneous context, the development of instruments, measurements and tools faithful to the original objects are fundamental to correctly reproducing and representing materials, contrast and colours of the works under analysis. In this work, we will analyse the main limits of colorimetry applied in cultural heritage domain considering a variety of applications on physical colour representation and on digital colour reproduction. We will focus on main state-of-the-art studies, regulations and guidelines for objects illumination, colour analysis and digitisation workflow showing some practical example of issues encountered by standard pointwise colorimetry.
