Advances in colour transfer

Abstract

Colour grading is an essential step in movie post‐production, which is done in the industry by experienced artists on expensive edit hardware and software suites. This paper presents a review of the advances made to automate this process. The review looks in particular at how the state‐of‐the‐art in optimal transport and deep learning has advanced some of the fundamental problems of colour transfer, and how far are we still from being able to automatically grade images.
