The human visual system (HVS) non-linearly processes light from the real world, allowing us to perceive detail over a wide range of illumination. Although models that describe this non-linearity are constructed based on psycho-visual experiments, they generally apply to a limited range of illumination and therefore may not fully explain the behavior of the HVS u…
The movie industry has been using Unmanned Aerial Vehicles as a new tool to produce more and more complex and aesthetic camera shots. However, the shooting process currently rely on manual control of the drones which makes it difficult and sometimes inconvenient to work with. In this paper we address the lack of autonomous system to operate generic rotary-wing d…
HDR Solution presentation
With the advent of ultra-high-definition TV services, high dynamic range (HDR) and wide color gamut (WCG) have become two highly desired image quality improvements for delivering immersive video experiences to the consumer mass market. Capture and rendering technologies have reached a level of maturity that now allows HDR and WCG enhanced video to be deployed ac…
The proposed Single Layer SDR backward compatible HDR video distribution solution detailed in this paper, named SL-HDR1, and standardized in ETSI TS 103 433 specification, aims at addressing these issues. SL-HDR1 leverages SDR distribution networks and services already in place. It enables both high quality HDR rendering on HDR-enabled CE devices, while also off…
As the video industry begins deployment of ultrahigh-definition TV in both professional and consumer markets, including support for higher dynamic range and wider color gamut services is considered essential within the industry. Higher dynamic range and wider color gamut offer end users a significantly enhanced viewing experience by supporting intensity ranges a…
This paper presents experimentation results related to adaptive video content mapping used as compression tool of HDR-PQ content. The purpose of adaptive video content mapping is to adapt the video signal dynamically depending on its statistical properties in order to better exploit the signal codewords range. Adaptive video content mapping has been investigated…
Live production workflows, particularly those for sports, employ complex pipelines to deliver HD, UHD, SDR, and HDR video streams. Because content originates as HDR or SDR, effective and flexible conversions are required between formats. Today, diverse tone mapping and inverse tone mapping technologies are proposed to the industry, each with the promise to creat…
