TLDR
To take advantage of HDR information even for traditional low-dynamic range displays, this work design tone mapping algorithms, which adjust HDR contrast ranges in a scene to those available in typical display devices.Abstract:
The main goal of High Dynamic Range Imaging (HDRI) is precise reproduction of real world appearance in terms of intensity levels and color gamut at all stages of image and video processing from acquisition to display. In our work, we investigate the problem of lossy HDR image and video compression and provide a number of novel solutions, which are optimized for storage efficiency or backward compatibility with existing compression standards. To take advantage of HDR information even for traditional low-dynamic range displays, we design tone mapping algorithms, which adjust HDR contrast ranges in a scene to those available in typical display devices.read more

Assessment of video tone-mapping: Are cameras' S-shaped tone-curves good enough?
Josselin Petit,Rafal Mantiuk +1 more
TL;DR: In this paper, the performance of video tone-mapping operators is investigated in a rating experiment using two criteria: overall quality and fidelity to real-world experience, which is measured for a range of parameter settings, revealing the importance of parameter fine-tuning and often unsatisfactory results of default operator parameters.

Properties and performance of a center/surround retinex
TL;DR: A practical implementation of the retinex is defined without particular concern for its validity as a model for human lightness and color perception, and the trade-off between rendition and dynamic range compression that is governed by the surround space constant is described.

TL;DR: The results demonstrate that the method is capable of drastic dynamic range compression, while preserving fine details and avoiding common artifacts, such as halos, gradient reversals, or loss of local contrast.
