A Computational Model of Human Colour Vision for Film Restoration

Even today, film restoration (both photographic and cinematographic) is a challenge, because it involves multidisciplinary competences: from analogue film inspection and conservation to digitisation and image enhancement. In this context, thanks to the high manageability of digital files, the film restoration workflow often follows a digitisation step, which presents many approximations and issues that are often ignored. In this work, we propose an alternative approach to the issues commonly encountered in film restora-tion (mainly concerning colour and contrast restoration) aiming at restoring the original colour appearance, through models of human colour perception.
