360° video, supporting the ability to present views consistent with the rotation of the viewer's head along three axes (roll, pitch, yaw) is the current approach for creation of immersive video experiences. Nevertheless, a more fully natural, photorealistic experience-with support of visual cues that facilitate coherent psycho-visual sensory fusion without the side-effect of cyber-sickness-is desired. 360° video applications that additionally enable the user to translate in x, y, and z directions are clearly a subsequent frontier to be realized toward the goal of sensory fusion without cybersickness. Such support of full Six Degrees-of-Freedom (6 DoF) for next generation immersive video is a natural application for light fields. However, a significant obstacle to the adoption of light field technologies is the large data necessary to ensure that the light rays corresponding to the viewer's position relative to 6-DoF are properly delivered, either from captured light information or synthesized from available views. Experiments to improve known methods for view synthesis and depth estimation are therefore a fundamental next step to establish a reference framework within which compression technologies can be evaluated. This paper describes a testbed and experiments to enable smooth and artefact-free view transitions that can later be used in a framework to study how best to compress the data.

3D crosstalk is a major contributor to 3D quality loss and visual fatigue on stereoscopic displays. This paper presents several 3D crosstalk measurement methods and discusses the coherence between methods, towards the derivation of meaningful quality indicators. It also identifies the need of synthetic indicators for complex crosstalk effects.

This document proposes a new, multi-primary projection system for prevention of illegal recordings in movie theaters. As of today, most camcorder-jamming methods tend to rely on either Infra-Red or spatial/temporal light modulations, both being easy to defeat using an appropriate filter system. Like Infra-Red, a metamerism-based system will modulate light magnitude depending on wavelength, but this time within the range of visible light, making jamming patterns harder to filter out. The mathematical model we use to solve our problem can actually serve as a generic model for all spectrum-based methods, including IR.

This document proposes a convenient theoretical analysis of light modulation-based systems for prevention of illegal recordings in movie theaters. Although the works presented in this paper do not solve the problem of camcorder piracy, people in the security community may find them interesting for further work in this area.

The current renaissance of 3D movies has drawn more and more attention from the audience. Three-dimensional television (3DTV) has been expected to be the next advance in television. Studies have shown that different people have different comfort range of depth in a 3D content, especially in 3DTV scenario, wherein much smaller screen sizes and viewing distances in home setup than in theater put more restrictions on the 3D content fed into the 3DTV. As a result, the version of the 3D content sent to home will not satisfy all the people in one family. In this paper, we try to solve this problem by providing a prediction of viewing discomfort of certain input content by certain viewer. Our method is based on the Disparity Discomfort Profile (DDP) built through subjective test for each viewer. The input content is analyzed by studying its disparity distribution. The prediction of discomfort is performed by matching the disparity distribution with the viewer's DDP. Then a mechanism to allow the viewers to adjust the depth range according to their visual comfort profile or viewing preference is used to minimize the discomfort. Experiments show promising results of the proposed method.
