Particularly in the film industry, the rapid development of display technologies has created an urgent need to develop fast, automatic gamut mapping algorithms. An article published on 14 November in the advanced online edition of the IEEE Transactions on Pattern Analysis and Machine Intelligence presents significant progress in this area.
A screen’s colour range is the set of colours it can reproduce. Wider screen formats can present more vivid and intense colours. The mapping of gamut or range is the process of adapting colours to the range of the screen to fully exploit the colour palette of the display device on which the content is shown, while preserving the artistic intent of the creator of the original content.
The goal of gamut mapping for film is to develop algorithms (gamut mapping algorithms, GMA) that reproduce the original content of the film insofar as possible respecting the artist’s vision, because this is an important feature that all GMA should have in order to be adopted by the film industry. “Therefore, for this study we performed psychophysical experiments to compare the performance of the proposed GMA with other methods in film conditions using a digital film projector (Barco-DP-1200 ) and a large projection screen”, the authors point out in their article.
