Image Vision & Immersion

Most of tomorrow's audio-visual formats increase the feeling of immersion in the content. The challenge is to transform the end user's experience by immersing him in the heart of the action or information. At the same time, computer vision technologies (augmented reality, virtual reality, volumetric video, etc.) are fed by progress in artificial intelligence. They are revolutionizing many industrial sectors by offering a new perception of the environment.

Many fields are concerned: media, training, collaborative work, surveillance, health, industry, web.

The Image Vision & Immersion laboratory builds tools that enable the adoption of these new technologies by professionals and the general public. It delivers expertise and technological bricks related to the characteristics and dimensions of the image (resolution, colorimetry, exposure, segmentation, compression...), sound (spatialization), and new rendering devices (screen, projection, headsets, and glasses for AR/VR in 3 or 6 degrees of freedom, holography...). These technologies allow the company to address different fields of application, from industry to medicine (in particular with industrial holography, augmented reality for health, etc.), from entertainment (television, cinema, etc.) to serious gaming (training, institutional, etc.), by placing the user at the heart of its thinking and its work, from the definition of needs to the use of the proposed solutions.

Fast view-specific generation of high-definition holograms with enhanced quality

Holography is often considered as the most promising immersive technology because it provides all the depth cues of the human visual system. Some limitations still need to be overcome such as the huge computational load of high-definition holograms and the noise introduced in the reconstructed scene during the quantization process. In this paper, we propose what we believe is a novel view…

Fast and flexible GPU implementation of the view-dependent error diffusion algorithm

During the quantization of the hologram values part of the information is lost, which introduces quantization noise in the reconstruction. To enhance the hologram quality, we developed in a previous work a view-dependent error diffusion algorithm which rejects the quantization noise in specific views. However, this algorithm is slow which prevents its use in real-time applications. In this paper,…

A comparative review of optical flow estimation methods for computer-generated holograms

Accurately estimating 3D optical flow in computer-generated holography poses a challenge due to the scrambling of 3D scene information during hologram acquisition. Therefore, to estimate the scene motion between consecutive frames, the scene geometry should be recovered first. Recent studies have demonstrated that a 3D RGB-D representation can be extracted from an input hologram with relatively…
