Light Fields and Light Stages for Photoreal Movies, Games, and Virtual Reality
This talk will present work from USC ICT and Google VR in creating actors and environments for movies, games, and virtual reality. The Light Stage computational illumination and facial scanning systems are geodesic spheres of inward-pointing LED lights which have been used to create digital actor effects in movies such as Avatar, Benjamin Button, and Gravity, and have recently been used to create photoreal digital actors based on real people in movies such as Furious 7, Blade Runner: 2049, and Ready Player One. The lighting reproduction process of light stages allows omnidirectional lighting environments captured from the real world to be accurately reproduced in a studio, and has recently be extended with multispectral capabilities to enable LED lighting to accurately mimic the color rendition properties of daylight, incandescent, and mixed lighting environments. They have also recently used their full-body light stage in conjuction with natural language processing and automultiscopic projection to record and project interactive conversations with survivors of the World War II Holocaust. Debevec will conclude by discussing the technology and production processes behind "Welcome to Light Fields", the first downloadable virtual reality experience based on light field capture techniques which allow the visual appearance of an explorable volume of space to be recorded and reprojected photorealistically in VR enabling full 6DOF head movement.
About the Speaker
Paul Debevec is a research professor at the University of Southern California and the associate director of graphics research at USC's Institute for Creative Technologies. Debevec's Ph.D. thesis (UC Berkeley, 1996) presented Façade, an image-based modeling and rendering system for creating photoreal architectural models from photographs. Using Façade he led the creation of virtual cinematography of the Berkeley campus for his 1997 film The Campanile Movie whose techniques were used to create virtual backgrounds in The Matrix. Subsequently, Debevec pioneered high dynamic range image-based lighting techniques in his films Rendering with Natural Light (1998), Fiat Lux (1999), and The Parthenon (2004); he also leads the design of HDR Shop, the first high dynamic range image editing program. At USC ICT, Debevec has led the development of a series of Light Stage devices for capturing and simulating how objects and people reflect light, used to create photoreal digital actors in films such as Spider Man 2, Superman Returns, and The Curious Case of Benjamin Button, and Avatar, as well as 3D Display devices for telepresence and teleconferencing. He received ACM SIGGRAPH's first Significant New Researcher Award in 2001, co-authored the 2005 book High Dynamic Range Imaging from Morgan Kaufmann, and chaired the SIGGRAPH 2007 Computer Animation Festival.

Tour of Laser Propagation Facilities at Kennedy Space Center
Additional Fee: $25 per person.
*Fee includes only transportation. Transportation will leave from the conference hotel and return to the Orlando International Airport and the conference hotel.
During this tour at Kennedy Space Center (KSC), you will see various facilities used for outside field experiments such as laser propagation measurements. The tour will include UCF’s Townes Institute Science and Technology Experimentation Facility (TISTEF), the Shuttle Landing Facility (SLF), and Vehicle Assembly Building (VAB). TISTEF is a site for experiments that require deployment in a fielded setting and consists of a 1 km grass range equipped with atmospheric monitoring instruments and multiple scintillometers as well as capabilities for optical tracking and remote sensing. From this site, slant path measurements can be made over the 13 km path to the top of the VAB. The 5 km long SLF is ideal for longer path measurements because of its homogeneity and flatness (earth’s curvature has been removed). This tour is possible because of the pcAOP committee and University of Central Florida.
Student Grand Challenge: the optical systems of the future
The challenge is open to OSA student members and their advisors interested in presenting concepts for enhanced machine visioning or systems that enhance the human vision system by augmenting or extending another human sense.
Individuals or teams are invited to submit ideas for either a novel passive or active optical system in the form of a 35-word abstract and 2 page summary highlighting the novelty, originality and feasibility of the concept. (Additional materials may include videos highlighting system mock-up or demos.)
Up to four finalists will be chosen to attend the Imaging and Applied Optics Congress, 25-28 June 2018 in Orlando, FL USA to present a 3-minute synopsis of their concept as well as to host a poster during the conference poster session. Finalists will receive a travel stipend up to $2,000 USD to cover airfare and hotel as well as full technical registration for the congress.
Two winners will be announced on-site and will receive a recognition plaque and a $250 prize.
Sponsored by Lockheed Martin and the OSA Foundation.
Passive Optical System Challenge Problem
The image processing community strives to duplicate human vision. For certain specific and well defined tasks we have succeeded or surpassed human capability, but still struggle with poorly defined and dynamic environments. The category comparison between machine vision and human vision include:
The passive optical systems challenge is to create a novel concept, technology or system for improving results in one of the 8 categories below:
- Spectrum: Machine vision is superior as human vision is limited to the visible spectrum. Machine vision is also more capable of seeing narrower spectrum steps and larger dynamic ranges than our eyes.
- Resolution: Human vision is superior. Current machine vision systems that are approaching 8K x 8K formats are starting to get there but, only with visible systems.
- Focus: Human vision is superior being able to focus from very close to very far with a single lens element. The eye aperture is limited by the size of the pupil for objects far away. Machine vision systems are specifically designed for very close or very far away and do not suffer from being aperture limited, but utilize many lens elements to accomplish the same human eye tasks.
- Optical Processing: Human vision + brain is superior to machine vision on pattern recognition and decision making.
- Image Processing: Ideas focused on detection and categorization of objects in the view field.
- Lens Technology: Ideas that are focused on optical sensors.
- High Speed Data Transport: Ideas that are focused on fast and efficient transport of high resolution image data and streams.
- Adaptable Lens Technology: Ideas that are focused on adaptable optical sensors.
- Liquid Lens Optical Sensors: Ideas focused on liquid lens.
- Artificial Intelligence: Ideas that focus on image based cognition
- AV/VR Technology: Ideas that are focused on Augmented and Virtual Reality technologies.
- Other: Ideas that do not fall into one of the existing categories.
Active Optical System Challenge
Given you have a human vision system, which is intrinsically passive, how would you use active sensing techniques to augment that vision system to mimic or extend the human senses? Augmentation could mean adding higher precision 3D vision, active foveae imaging, active IR assisted sensing, vibrometry, polarimetry, sensing motion in the FOV, chemical/biological sensing, looking through fog/turbulence, etc. Many such systems have been demonstrated, but they are often large, heavy, and costly.
The active optical system challenge is to come up with novel sensor concepts that mimic at least two of the human senses at a distance of at least 10 m, with the sensor fitting into one third of the human brain (roughly 0.5 liters). More sensing modalities are encouraged, especially those that extend what humans can do.
- Sight (e.g., producing 2D or 3D images)
- Hearing (e.g., measuring object vibrations through optical means)
- Smell (e.g., chemical/biological sensing)
- Taste (e.g., chemical/biological sensing)
- Touch (e.g., characterization of surface texture and/or temperature)
- Limited to undergraduate or graduate students.
- The teams should be composed of at least one OSA student member and at least one advisor who is an OSA member.
- Required submission format: PDF with a 35-word abstract and 2 page summary.
- Optional submission material: videos, system mock-ups, demonstrations.
- Compliance: is the idea submission complete and does it comply with the rules of the challenge?
- Novelty: does the idea describe a novel approach to providing a solution?
- Originality: how original is the proposed technology or use of existing technology?
- Relevance: How well does the idea relate to the topic and provide a solution aligned with the goals of this challenge?
- Feasibility: how likely can the idea be prototyped?
Submissions will be evaluated by a committee of Imaging and Applied Optics Congress leadership and Lockheed Martin executives.
