Transforming Heritage: Formats, authenticity and preservation / Recent and emerging JPEG formats

ICA Webinar - Transforming Heritage: Formats, authenticity and preservation / An overview of recent and emerging JPEG formats for digital archival and long-term preservation
The third session, took place on 15 November 2024, was facilitated by Touradj Ebrahimi, Professor at Swiss Federal Institute of Technology in Lausanne (EPFL), heading its Multimedia Signal Processing Group. He is also the Convenor of JPEG standardization Committee. He was adjunct Professor with the Center of Quantifiable Quality of Service at Norwegian University of Science and Technology (NTNU) from 2008 to 2012. His research interests include still, moving, and 3D image processing and coding, visual information security (rights protection, watermarking, authentication, data integrity, steganography), new media, and human computer interfaces (smart vision, brain computer interface).
Summary
The webinar starts with a description of the recently published HTJ2K, JPEG XL, and JPEG AI image coding formats, emphasizing the features each offers that make them particularly attractive for storage, distribution, visualization, and interactions in archival and long-term preservation applications. We then discuss JPEG Pleno Point Cloud Coding, which is expected to be published as an International Standard by ISO and IEC in early 2025, and can be used to code 3D content, represented as point clouds, among others in archival and preservation applications. The webinar will end with a look into an emerging standard known as JPEG DNA, an image format for archival on DNA support, by motivating the reasons behind this effort and its roadmap.
