Chapter 9 - Vision models for tone mapping in cinema

Abstract

Based on recent findings and models from vision science, we present in this chapter effective tone mapping and inverse tone mapping algorithms for production, post-production and exhibition. These methods are automatic and real-time, and they have been both fine-tuned and validated by cinema professionals, with psychophysical tests demonstrating that the proposed algorithms outperform both the academic and industrial state-of-the-art. We believe these methods bring the field closer to having fully automated solutions for important challenges for the cinema industry that are currently solved manually or sub-optimally. As in the case of gamut mapping, we also show that state-of-the-art image quality metrics are not capable of predicting observers' preferences for tone mapping and inverse tone mapping results.
