Abstract

This document provides an overview of the 32nd Stereoscopic Displays and Applications conference and also serves as an introduction to the conference proceedings.

Introduction

The 32nd annual Stereoscopic Displays and Applications (SD&A) conference was very different to all previous SD&A conferences because it was held fully online. The 2020 SD&A conference was fortunate to just clear the start of the widespread outbreak of the COVID-19 pandemic, but no such luck for the 2021 conference. The 2021 SD&A conference was originally planned to be held in downtown San Francisco, however it was soon obvious this was not going to be possible, and "the show must go on" so the IS&T and conference chairs worked very hard to quickly pivot the SD&A conference, and the whole Electronic Imaging (EI) Symposium, to a fully online format.

The online version of the Electronic Imaging Symposium necessitated some careful adjustments to the schedule since attendees were located all around the world in almost every time zone. The first adjustment was to hold the symposium over a period of three weeks (11-28 January), rather than the usual five days. This created a more relaxed schedule which allowed more flexibility. The first week was short courses, and week two and three were the conference presentation sessions.

The other adjustment was that the daily schedule was split into a US East Coast morning session (which was also convenient for attendees in Europe) and a (US East Coast) late afternoon/evening session (which was also convenient for attendees in the Asia/Pacific region). Of course, some of the sessions would occur at an inconvenient time for some of the attendees so all presentations were recorded and made available for offline viewing.

The online format used a range of different session types to try to reproduce the friendly and personable atmosphere that EI is known for. As well as the online presentation sessions which allowed for real-time question and answer option for the audience, as well as break-out rooms, demonstration sessions, and also a Discord channel for online chat.

This introduction document provides a summary of the wide range of activities and events that took place at the 2021 online conference. One thing that didn't change was that the conference still attracted a strong mix of attendees from both industry and academia including those who spoke in the plenaries, keynotes and technical sessions.

This year the conference had 21 oral presentations across the three days of the conference. Two of the conference sessions were held jointly with the Engineering Reality of Virtual Reality conference (ERVR).

The final conference program is available on the long-running SD&A conference website:
    www.stereoscopic.org/2021

The program page also lists which presentations have an accompanying manuscript (and where to find it) and those that don't. Some of the papers are published in the Journal of Imaging Science and Technology (JIST) and are indicated with the designation "JIST first" since manuscripts submitted this way go through an accelerated full review process.

All of the published manuscripts from SD&A 2021 along with the other papers from the 2021 Electronic Imaging Symposium will be published in the IS&T Digital Library on the Ingenta Connect platform at:
    http://ist.publisher.ingentaconnect.com/content/ist/ei

Papers in the joint sessions can only appear in one proceedings volume so they may appear in the proceedings volume of one of the contributing conferences rather than the SD&A proceedings. The SD&A 2021 program page will provide a direct link to each of the manuscripts without needing to worry about which particular conference or journal site they appear in – just visit:
    www.stereoscopic.org/2021

All manuscripts from the SD&A 2021 conference and the wider Electronic Imaging Symposium are published Open Access which significantly improves the accessibility of SD&A authors' work and help you, the reader, access new and important developments in this field. As well as the conference sessions running fully online, the technical short course "Stereoscopic Imaging Fundamentals" hosted by Andrew Woods also ran online over two days, and perhaps even more challenging, the annual 3D theater session also ran online.

SD&A 3D Theater Session

The 3D Theater session has been a regular fixture of the SD&A conference for the past 20+ years, and with the move of this year's conference to an online event it provided an opportunity for us to do something different this year. Thanks to the organisational efforts of lead-producer John Stern, expert online production by Eric Kurland, and production assistance by Dan Lawrence, this year's 3D Theater session was also held fully online and attendees were able to watch the SD&A 3D Theater session films from the comfort of their loungeroom. The films screened in the 2021 3D Theater session were selected from winning films over the past ten years of the SD&A 3D Theater session. The event was "broadcast" live on YouTube in both anaglyph 3D (for people to watch using red/cyan anaglyph glasses) and over-under 3D formats (for people to watch on a 3DTV), and was hosted by Eric Kurland in 3D from his studio in Los Angeles, along with a 3D cross to Andrew Woods in Australia for the introduction.

There were three identical staggered "live-stream" screenings of the 3D Theater session timed to suit attendees in the Americas, Europe, and Asia. The session was free and open to public, and started Saturday 16 January.

    The 3D films, and which SD&A award they won, are listed below:
  • 1. Stereo: A Love Song to 3D, Creator and star: Robert Bloomberg; Motion graphics and co-animator: Pad McLaughlin (USA), Winner 2018 Animation Award.
  • 2. Albuquerque Balloon Festival – Mass Ascension, John Hart (USA), Winner 2019 Live Action Award.
  • 3. White Knuckles, OK Go, OK Go (USA), Winner 2011 Live Action Award.
  • 4. Amongst, Chisa Hidaka and Benjamin Harley (USA), Winner 2016 Live Action Award.
  • 5. Chlamydomonas reinhardtii 3D – From Biological Cells to Biofuels, Niklas Biere, Bjorn Sommer (Germany / Australia), Winner 2016 Animation Award.
  • 6. ENT3D Project Explained, Peter J. Casano, M.D. (USA), Winner 2020 Hybrid Award.
  • 7. Chrysalis, Ina Conradi and Mark Chavez (Singapore), Winner 2017 Animation Award.
  • 8. Ninety Three Million Miles, Site-Eye Time-Lapse Films (dir: Brian McClave and Gavin Peacock) (UK), Winner 2013 Live Action Award.
  • 9. The Simple Carnival – Go Away I Like You Too Much, Jeff Boller (USA), Winner 2019 Animation Award.

  • 12. Morpheos Trailer, John Hart (USA), Winner 2014 Animation Award.
  • 13. Formosa 3D, Charlie Chu (Taiwan), Winner 2018 Live Action Award.
  • 14. Cochemare, Chris Lavis and Maciek Szczerbowski (Canada), Winner 2015 Animation Award.
  • 15. All Is Not Lost, OK Go and Pilobolus (USA), Winner 2012 Best of Show Award.
  • 16. The Whitewashing of 5 Pointz, Ben Schwartz (USA), Winner 2015 Live Action Award.
  • 17. Little Planet in Stereoscopic 3-D, STEREOeYe / Takashi Sekitani (Japan), Winner 2020 Live Action Award.

The event was well attended and received very good feedback from attendees. There were 185 event registrants via Eventbrite, and the screening on YouTube received the following attendance numbers of the two format options combined:
  o   Screening 1 (New York): 77
  o   Screening 2 (Tokyo): 33
  o   Screening 3 (Paris): 57
  o   Total: 167

The approximate mix of viewers watching in Full-3D vs. anaglyph was: 60% / 40%. An informal favorite amongst the producers was "All is Not Lost" – see Figure 1. In 3D the film had a special extra dimension – pardon the pun.

First Day

The first day of the conference had five technical sessions – three in the morning and two in the evening.

The conference kicked off with a special invited session with two presentations. The first technical presentation of SD&A 2021 was titled "Looking back at a wonderful decade shooting live-action 3D" by Demetri Portelli, I.A.T.S.E. International Cinematographer's Guild (Canada) – see Figure 2. His presentation built upon his experience working on multiple high-budget high-profile 3D movies as stereographer or stereoscopic supervisor.

The second presentation of SD&A Invited session was titled "When 3D headache will be over: A decade of movie quality measurements" by Dmitriy Vatolin, Lomonosov Moscow State University (Russian Federation) – see Figure 3. Dmitriy and his colleagues have been doing an amazing amount of work analysing and quantifying stereoscopic alignment anomalies and other metrics in theatrically released 3D films, and this presentation overviewed this work.

Completing the morning session were two sessions on "Stereoscopic Developments" and "Stereoscopic Displays, Cameras, and Algorithms".

In the evening session things kicked off with a session on "Autostereoscopic Displays" followed by the conference's second keynote presentation, this time "Underwater 3D system for ultra-high resolution imaging" by Pawel Achtel from Achtel Pty Limited (Australia) – see Figure 4. Pawel's presentation provided an important insight into the technology and analysis behind obtaining high-quality underwater 3D visuals for the three Avatar movie sequels and other projects.

Second Day

The second day of the conference started with a symposium-wide plenary session titled "Deep internal learning—Deep learning with zero examples" by Michal Irani, Professor in the Department of Computer Science and Applied Mathematics at the Weizmann Institute of Science (Israel).

In the evening there was an SD&A session on "Stereoscopic Content and Quality", a short demonstration session for one of the papers, and the second SD&A Keynote presentation on "Digital Stereoscopic Microscopy" by Michael Weissman, SB3D Technologies, Inc. (United States) – see Figure 5. Michael's presentation discussed the history of stereoscopic microscopy and future opportunities with new design techniques.

Third Day

The third day of the SD&A conference started with the second symposium-wide plenary session titled "The development of integral color image sensors and cameras" by Kenneth A. Parulski, Expert Consultant: Mobile Imaging (United States).

In the evening there were two technical sessions of the Engineering Reality of Virtual Reality conference titled "Immersive Experiences" and "VR and 3D Applications" held jointly with the SD&A conference.

Demonstration Session

The 2021 SD&A Demonstration Session was held 6-8pm New York time on Wednesday 20 January. This year our Demonstration Chair Bjorn Sommer outdid himself by using a new online platform called "Gather.Town" to hold the session. The Demonstration Session has been an incredibly important part of the SD&A conference for almost the entire 32-year history of the conference. The Demonstration Session provides the opportunity for attendees to meet individually with authors, look at and hear about new technologies, and informally bump into other conference attendees and chat. Most online conference platforms don't reproduce this type of atmosphere – mostly being suitable for lecture, seminar or workshop type environments, but Gather.Town allows users to see each other in the hall but only talk to them via video and audio when they approach each other.

In preparation for the session, Bjorn setup a map which reproduced the look of the usual SD&A Demonstration Session hall – as can be seen in Figure 6. Presenters have tables around the hall and they are able to chat with attendees when approached. Of course, this is all reproduced digitally. All attendees and presenters have an animated character they can ‘walk' around the map. When two (or more) characters approach each other (within a nominated range) an audio/video channel is activated, and they can see each other and talk to each other. The power of the platform is that multiple conversations can be happening in parallel without interrupting each other. Each of the presenters can be individually video-chatting with people at their booth, and equally attendees in the central part of the hall who are close to each other can be chatting to each other there too.

    This year the demonstration session presenters and their demonstrations were:
  • Takashi Kawai from Waseda University (Japan) introduced an award ceremony held in a virtual space by the Japan Chapter of the Advanced Imaging Society titled "Application of 3D Avatars in a Virtual Event"
  • Chris Ward and Dan Lawrence from DepthQ (USA) demonstrated their DepthQ VR AQUA experience (see Figure 7).
  • Bjorn Sommer from the Royal College of Art (UK) presented the working prototype for his paper Hybrid Stereoscopic Photography - Analogue Stereo Photography meets the Digital Age with the StereoCompass app" (see Figure 8).
  • Andrew Woods from Curtin University (Australia) demonstrated the method of testing passive-polarised 4K 3D TVs for correct operation using a simple test pattern.
  • Eric Kurland from 3-D Space Museum (USA) demonstrated his live 3D video streaming studio solution which he used for the 2021 SD&A 3D Theater Session (see Figure 9,10,11).
  • Pawel Achtel from Achtel.com (Australia) presented his 3D Film Services and Equipment for Giant Screen and IMAX Cinema.

During the demonstration session attendees could be seen wandering the hall, visiting all the booths, and having a fun time chatting with exhibitors – all whilst in lock-down.

Second Week

In the subsequent week, as well as more EI conferences and more EI technical presentations, there were two additional symposium-wide plenary presentations:
- "Making invisible visible" by Associate Professor Ramesh Raskar, MIT Media Lab (United States), and
- "Revealing the invisible to machines with neuromorphic vision systems: Technology and applications overview" by Luca Verre, CEO and Co-Founder at Prophesee (France).

Importantly the EI Symposium was also very pleased to be able to award Professor Raskar with the 2021 Electronic Imaging Scientist of the Year Award! (See Figure 12) Professor Raskar presented a keynote presentation at the SD&A conference in 2011 and we were very pleased to see him receive this year's award.

Discussion

Many individuals and companies contribute each year in various ways to make the SD&A conference a successful event. Most importantly, we thank the conference authors and attendees, who make this meeting such a successful event.

We are grateful to all of the providers of 3D content for allowing their content to be shown to the conference audience at the 3D Theater Session.

The conference committee plays an important role throughout the year, ensuring the correct technical direction of the meeting. Sincere thanks go to our founding chair, John Merritt, and our committee: Neil Dodgson, Justus Ilgner, Eric Kurland, Bjorn Sommer, John Stern, Chris Ward and Laurie Wilcox.

Thanks also to the staff at IS&T - the organizing society instrumental in organizing all manner of aspects for the meeting – and in particular Suzanne Grinnan, Marion Zoretich, Ann McCarthy and Donna Smith.

This was a very different year for SD&A so we wish to thank everyone for adapting so quickly to the new circumstances and attending virtually. Despite the rolling time zones, some of our attendees attended all of the SD&A sessions, regardless of their regular sleeping pattern.

Conference activities do not stop at the end of the annual meeting. The SD&A conference website and LinkedIn group provide a focus for conference activities during the time between conferences. We will soon be actively seeking abstracts for the 2022 conference, with a submission deadline in mid-2022 – see the Electronic Imaging website www.ElectronicImaging.org and the SD&A website www.stereoscopic.org for details and deadlines.

The SD&A website also has an extensive collection of photographs highlighting the activities of past conferences. In addition, the website hosts the stereoscopic virtual library, which contains several historically important books that have been digitized, in full, into PDF format, and are available for free download.

The SD&A conference maintains a Tweeter feed at @SDnAconf to keep everyone informed about SD&A events and activities. Check out the conference Twitter feed for details:
