Computational Color Imaging Workshop (CCIW) – Interim

Before the in-person workshop planned in Lyon for 2023, a short edition is proposed online. Created in 2007, the Computational Color Imaging Workshop is a premier international forum on color image capturing, color image processing, color image quality assessment, color vision modeling, color image rendering, and color image reproduction. The workshop presents a state of the art and pioneering research works in these fields.

9 June 2022 – 9:00 – 12:30 (Paris – CET), 16:00 – 19:30 (Tokyo – JST)

10 June 2022 – 9:00 – 12:30 (Paris – CET), 16:00 – 19:30 (Tokyo – JST)

How to connect




Created in 2007, the Computational Color Imaging Workshop is a premier international forum on color image and advanced types of images (spectral, 3D, etc.), including acquisition, processing, rendering, quality assessment, analysis, reproduction. The workshop also adresses color vision, and material appearance. Applications in many fields are concerned: Computer vision, health and beauty, arts and design, video and display, printing and manufacturing, remote sensing, natural sciences, etc.

The workshop presents a state of the art and pioneering research works in these fields:

  • Color vision
  • Color, spectral, 3D imaging
  • Computer graphics
  • Computational lighting
  • Color image/video quality
  • Physical modeling for color
  • Color image reproduction
  • Digital printing and fabrication
  • Secured image
  • Material Appearance
  • Color acquisition, calibration and display


  • Mathieu Hébert, Université Jean Monnet Saint-Etienne, France
  • Shoji Tominaga, Norwegian University of Science and Technology, Norway
  • Raimondo Schettini, Università degli Studi di Milano-Bicocca, Italia
  • Alain Trémeau, Université Jean Monnet Saint-Etienne, France

Call for papers

Speakers and attendees are all invited to submit a paper to the MDPI Journal of Imaging, which will be published, if accepted after peer review, into a special issue Selected papers from CCIW. Submit your contribution through : https://www.mdpi.com/journal/jimaging/special_issues/CCIW

Journée d’étude à Poitiers : Imager les œuvres d’art

Rendre compte à une date donnée de l'état d'un objet du patrimoine, suivre son évolution dans le temps, comprendre ses propriétés matérielles, structurales, optiques ou visuelles... autant d'enjeux cruciaux pour les historiens d'art, les conservateurs, les restaurateurs ou les archéologues que les techniques d'imagerie et de reconstruction 3D permettent aujourd'hui d'aborder. Cette journée d'étude vise à dresser un catalogue des recherches en cours dans ce domaine.
