Virtual Reality and Immersive Media

Virtual Reality (VR) and 360 video are reshaping the media landscape, changing our daily lives and the way we interact with each other. They are creating a fertile business environment, enabling new social and interactive VR formats, where viewers connect more empathically with the content and with others. The combination of photorealistic capture techniques and immersive displays result in a new set of research challenges. In particular, DIS focuses on novel strategies for compression and transmission of real-time reconstructed 3D data in Internet infrastructures, and on the objective and subjective evaluation of such technologies. Our work, partly distributed as open source, has led to the start of a consumer industry standardization activity in Moving Picture Experts Group (MPEG) on point cloud compression, serving as the basis to generate the anchors included in the recent call for proposals. All these activities and results position DIS as a leading expert on immersive media technologies and QoE evaluation.
