A manifesto on the future of image coding - JPEG Pleno

A manifesto on the future of image coding - JPEG Pleno
Touradj Ebrahimi
JPEG Convener

Tremendous progress has been achieved in the way consumers and professionals capture, store, distribute, display and ultimately use images. We have been witnessing an ever growing acceleration in creation and usage of images in all sectors, applications, products and services. This widespread and still growing use of images has brought new challenges for which solutions should be found. Among others, image annotation, search and management,  imaging security and in particular privacy, efficient image storage, seamless image communication, new imaging modalities, and enhanced imaging experiences are  just a few examples of challenges to which scientific community, industry, service providers, and entrepreneurs have responded in the past, including continuing improvement of existing solutions and creating new ones.

During 25 years, Joint Photographic Experts Group (JPEG) has been an example of such efforts, and has offered image coding standards which can cope with some of the above challenges. This has resulted in a series of successful and widely adopted coding algorithms and file formats such as JPEG and JPEG 2000.

JPEG format is today a synonymous of modern digital imaging, and one of the most popular and widely used standards in the history. Images created in JPEG format now exceeds 1 billion per day in their number, and most of us can count a couple, if not more JPEG engines in devices we regularly use in our daily lives; in our mobile phones, in our computers, in our tablets, and of course in our cameras. JPEG ecosystem is strong and continues an exponential growth for the foreseeable future. A significant number of small and large companies created in the last two decades have been relying on JPEG format, and this trend will likely continue.

A question to ask our selves is: will we continue to have the same relationship to flat snapshots in time (the so-called Kodak moments) we call pictures, or could there be a different and enhanced experience created when capturing and using images, that could go beyond the experience images have been providing us for the last 120 years?

Several researchers, artists, professionals, and entrepreneurs have been asking this same question and attempting to find answers with more or less success. Stereoscopic and multi-view photography, panoramic and 360-degree imaging, image fusion, points cloud plus texture imaging, high dynamic range imaging, integral imaging, light field imaging, and holographic imaging are among exemples of solutions that have been proposed as future of imaging.

The offered experience based on the above solutions obviously depends largely on the state of the maturity of technologies behind them, and their implementation, including the content created by them, the type of usage and relationship they offer to professionals and consumers. It is normal to expect that with enough efforts and resources, as well as enough time, some will have the potential of reaching a level of maturity that can make them good candidates to offer an experience beyond what exists today.

However, the way such solutions are introduced has probably as much importance as the solutions themselves. The JPEG ecosystem is huge, and offers sufficient experience for what it is expected to offer. The legacy that JPEG brings should not be underestimated. In fact, several attempts have been made in the past by companies, as well as by standardisation organisations, including the JPEG committee itself, to replace the JPEG format by an alternative. Success has been limited if not inexistent in many of such attempts.

Introduction of new imaging experiences should therefore be done in a smooth and gradual way without disruption of the existing JPEG ecosystem, but by enhancing it for those wanting it, while still offering the old experience to those who don't. JPEG backward compatible standards are therefore essential in introduction of new imaging standards, and should be given the attention they deserve, when assessing future image coding standards.

Recently, JPEG standardisation committee has created an initiative called JPEG Pleno. “Pleno” is a reference to “Plenoptic” a mathematical representation, which not only provides color information of a specific point in a scene, but also how it changes when observed from different directions and distances. “Pleno” is also the latin word for “complete”, a reference to the vision of the JPEG committee that believes future imaging will provide a more complete description of scenes well beyond what is possible today.

The road-map for JPEG Pleno follows a path that starts in 2015 and will continue beyond 2020, with the objective of making the same type of impact that the original JPEG format has had on today's digital imaging starting from 20 years ago. Several milestones are in work to approach the ultimate image representation in well-thought, precise, and useful steps. Each step could potentially offer an enhanced experience when compared to the previous, immediately ready to be used in applications, with backward compatibility. Backward compatibility could be either at the coding or at the file format level, allowing an old JPEG decoder of 20 years ago to still be able to decode an image, even if that image won’t take full advantage of the intended experience, which will be only offered with a JPEG Pleno decoder. Examples of potential milestones include panoramic and 360-degree images, fused images, and light-field images. Stay tuned as JPEG committee clarifies and shares its plans and achievements for JPEG Pleno in the coming months and if you want to join this effort, do not hesitate to drop me an email to

Touradj Ebrahimi Elected as JPEG Convener

The Joint Photographic Experts Group (JPEG) is a Working Group of ISO/IEC, the International Organisation for Standardization / International Electrotechnical Commission, (ISO/IEC JTC 1/SC 29/WG 1) and of the International Telecommunication Union (ITU-T SG16), responsible for the popular JPEG, JPEG 2000, JPEG XR, JPSearch and more recently, the JPEG XT, JPEG Systems and JPEG AR families of imaging standards. The WG1 group meets nominally three times a year, in Europe, North America and Asia. The latest meeting was held on July 7 – 11, 2014 in Sapporo, Japan.

Touradj Ebrahimi has been elected as the new Convener of JPEG Committee. He has a longstanding involvement in JPEG, MPEG and SC29 standardisation committees and was currently acting as the Chairman of Advisory Group on Management in SC29. Touradj EBRAHIMI received his M.Sc. and Ph.D., both in Electrical Engineering, from the Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland, in 1989 and 1992 respectively. In 1993, he was a research engineer at the Corporate Research Laboratories of Sony Corporation in Tokyo, where he conducted research on advanced video compression techniques for storage applications. In 1994, he served as a research consultant at AT&T Bell Laboratories working on very low bitrate video coding. He is currently Professor at EPFL heading its Multimedia Signal Processing Group. He was also adjunct Professor with the Center of Quantifiable Quality of Service at Norwegian University of Science and Technology (NTNU) from 2008 to 2012.

“I am honoured to be elected as the new Convener of the JPEG standardisation committee. Billions of images are produced on daily basis in JPEG formats and hence I considered it as a huge responsibility to take care that the committee keeps on supporting digital imaging ecosystem and to assure support for functionalities required by future applications and imaging devices.” said Prof. Touradj Ebrahimi, the new Convener of the JPEG committee.

At this opportunity, the JPEG Committee wishes to thank the former WG 1 Convener Dr. Daniel Lee (US) for his leadership and vision in the development of the JPEG family of standards. WG 1 wishes to express its deepest thanks and appreciation for his effort and dedication over the last 18 years.

“It was an honour to serve as JPEG Convener over the past 18 years. It was an interesting journey to manage the very successful standards developed by the JPEG Committee. I am convinced that Prof. Touradj Ebrahimi is well placed to continue this endeavour.” said Dr. Daniel Lee, former Convener of the JPEG committee.

The next (67th) WG 1 Meeting and its ad hoc group meetings will be held on October 20-24, 2014, in Strasbourg, France.

More information about JPEG and its work is available at or by contacting Peter Schelkens and Fumitaka Ono of the JPEG PR ad hoc group at
