Audiovisual communications that feel real
The aim of the VISION project, in which the UPC-Barcelona Tech is involved, is to enhance digital and audiovisual communication systems to make virtual meetings increasingly resemble face-to-face meetings.

Audiovisual and image media, especially images of the human face, most faithfully represent real communication. Despite this, communication systems such as current video conferencing platforms have not managed to replace face-to-face meetings, as they are unable to give a true feeling of reality and presence to users.
The VISION project, led by Telefónica I+D and in which the UPC-Barcelona Tech is involved, aims to make a leap in the quality of digital video communications, also called next generation video communications.
In order to make virtual communications feel like face-to-face meetings, Telefónica I+D has reached an agreement with the Video and Image Processing Group, based at the UPC-Barcelona Tech’s Department of Signal Theory and Communications, to develop technologies for capturing multi-view video images that generate 3-D models of reality. The Group is developing volumetric analysis techniques that will segment scenes to separate the background of the images in the foreground. The elements that do not form part of the background of a scene are then reconstructed in 3-D. Automatic gesture recognition tools are also being examined to build gesture interfaces with a video conferencing system or to extract semantic information.
Looking around us, we will be able to see and hear the people we are talking to as if they were there, even if they are far away. We will share a space in terms of acoustic and visual stimuli that gives the impression that we are physically together in the same place. The high quality and realism required for these systems mean that research must be conducted into advanced audiovisual technologies so that an interconnection can be made between remote “environments” through communication networks.
The Optical Communications Group and the Audiovisual Technologies Group, both based at the UPC-Barcelona Tech, will also take part in this project, which falls within the framework of the CENIT (National Strategic Consortia for Technical Research) Programme, in which 13 Spanish companies led by Telefónica I+D are involved. It is anticipated that VISION will be completed in 2010.
