4th JPEG DNA Workshop Proceedings
July 13, 2021

The JPEG Committee has decided to explore efficient image coding approaches for applications where DNA is used as storage support. One such application is long term preservation of media content. Because of its past successful history of offering efficient image and image sequence formats for storage and archival applications, the JPEG committee is well positioned to address standardization challenges related to multimedia content efficient representations and, in particular, for image and image sequences in the context of DNA storage.

As a minimum, JPEG committee could launch an activity to convert its existing image coding formats from compressed binary representation to compressed “AGCT” quaternary representation. Standardized image coding approaches along with appropriate tools such as error resiliency and associated metadata, particularly suited to the DNA digital information storage requirements, are also good directions for JPEG to explore. As an immediate step, the DNA digital information storage applications need to be explored more in detail with particular emphasis on image and image sequences as information. They should then be prioritized in terms of time to market and maturity with efforts primarily focusing on specific use cases that can gather a critical mass of stakeholders. A first, second and third online workshop were organised to launch such an exploration.

In order to continue gathering input from stakeholders, a fourth workshop has been organised on Friday, 2 July 2021. This workshop was organised as part of an Ad Hoc Group that has been created to carry out the above objectives.
