Warsaw, Poland – June 23rd, 2015

The JPEG Committee has launched a new activity: JPEG Pleno, which is targeting a standard framework for the representation and exchange of new imaging modalities such as – but not limited to – light-field, point cloud and holographic imaging. In addition to the representation it is also a target to define new tools for improved compression while providing advanced functionality support for image manipulation, metadata, image access and interaction, privacy and security. This paradigm shift caused by computational imaging approaches will be as disruptive for the photography markets as the migration from analog film to digital pictures. Hence, JPEG Pleno investigates how this evolution can be properly addressed while taking into account JPEG’s legacy formats.

Since the JPEG committee intends to interact closely with actors in conventional and emerging imaging solutions, a workshop was organised during the JPEG meeting in Warsaw, Poland that was targeted to understanding industry needs in terms of technology and supported functionalities. Below, the workshop program is listed as well as download links for the presentations.
