Gamut extension for cinema: psychophysical evaluation of the state of the art and a new algorithm

Syed Waqas Zamir, Javier Vazquez-Corral, Marcelo Bertalmío, Bernice E. Rogowitz, Thrasyvoulos N. Pappas, Huib de Ridder
2015 Human Vision and Electronic Imaging XX  
Wide gamut digital display technology, in order to show its full potential in terms of colors, is creating an opportunity to develop gamut extension algorithms (GEAs).  ...  First we report a psychophysical evaluation of GEAs specifically for cinema using a digital cinema projector under cinematic (low ambient light) conditions; to the best of our knowledge this is the first  ...  Last but not least, the authors would like to express their gratitude to Barco N.V. for their invaluable help, without which this work would not have been possible.  ...

21.3: New Metric for Display Color Gamut Evaluation

Moshe Ben Chorin, Dan Eliav, Shmuel Roth, Assaf Pagi, Ilan Ben-David
2007 SID Symposium Digest of Technical Papers  
We suggest a metric for evaluating color gamut of displays based on summing the probability of using a certain part of the display color gamut multiplied by an impact parameter for that color region.  ...  We further present methods for evaluating the probability of use, and the impact of color.  ...  In particular, for home cinema and TV applications a logical design target should be the cinema color gamut.  ...

Vision Models for Wide Color Gamut Imaging in Cinema

Syed Waqas Zamir, Javier Vazquez-Corral, Marcelo Bertalmio
2019 IEEE Transactions on Pattern Analysis and Machine Intelligence  
Our experiments also highlight the limitations of existing objective metrics for the gamut mapping problem.  ...  In this paper we propose a novel framework that is based on vision science models, performs both gamut reduction and gamut extension, is of low computational complexity, produces results that are free  ...  Special thanks to Dirk Maes from Barco N.V. and to Stephane Cattan from Deluxe-Spain for their invaluable help and unwavering support.  ...

Gamut mapping for visual attention retargeting

Javier Vazquez-Corral, Marcelo Bertalmío
2017 Final program and proceedings (Color and Imaging Conference)  
In short, visual attention retargeting can be achieved by performing gamut extension in those regions that we want to highlight and gamut reduction in the other regions.  ...  In this work, we show that we can pose the visual retargeting problem in terms of gamut mapping.  ...  We run our method in RGB color space for gamut reduction and CIELAB color space for gamut extension with the parameters proposed in [20] and [18] , respectively.  ...
