Descripción del proyecto
Una gama pionera de mapeo automatizado para uso profesional, móvil y web
Los consumidores exigen cada vez más imágenes y videos realistas, tanto en sus teléfonos móviles, como en los televisores o los cines. Cuando los colores que hay que reproducir se encuentran fuera de la gama o las capacidades del sistema de visualización, se utiliza el mapeo de la gama para modificar los colores originales y optimizar la pantalla. El proyecto GAMMAVISION, financiado con fondos europeos, fabrica una serie de productos que presentan el método automático de mapeo de gama basado en la visión, desarrollado previamente por el equipo, que ha demostrado ser mejor que los algoritmos vanguardistas en cuanto a las preferencias de los usuarios. Los resultados incluirán una aplicación web gratuita y aplicaciones comerciales para sistemas iOS y Android, así como complementos comerciales para «software» de posproducción fotográfica y películas profesionales.
Objetivo
The color gamut of a display is the set of colors that it can reproduce: screens with wider gamuts are capable of presenting more vivid, intense colors. Different display technologies have different gamuts, from the narrow gamut of TV sets to the wide gamut of cinema and the ultra-wide gamut of laser projectors. Gamut mapping is the process of adapting the colors of an image to the gamut of the display where it is shown, and it is an essential process at every step of the imaging chain: cameras perform automatic gamut reduction, in movie postproduction colorists perform gamut mapping manually, and emerging display technologies perform automatic gamut extension. There is a trade-off between speed and quality, and no method, be it automatic or manual, is exempt from issues. One of the research outcomes of the applicant’s ERC Starting Grant IP4EC is a vision-based gamut mapping method that is automatic, of extremely low computational complexity, and produces images and videos that look natural, without any halos, spurious colors or artifacts. The model has been validated confirming that it outperforms state of the art algorithms in terms of users’ preference. A European patent application has been filed. The core idea for this Proof of Concept proposal is to make a series of products that highlight the capabilities of our gamut mapping method on three distinct scenarios: image and video capture, professional post-production of photography and cinema, and image and video display. Specifically, this project will produce, in a B2C commercial approach, a free web application and commercial mobile apps for iOS and Android systems intended for the general public, plus commercial plug-ins for professional movie and photo post-production software. We will formulate a business plan around these products, that also show the potential of our model for other applications for which we intend to license our technology and provide services, in a B2B commercial approach.
