Computational photography has become an increasingly active area of research within the computer vision community. Within the few last years, the amount of research has grown tremendously with dozens of published papers per year in a variety of vision, optics, and graphics venues. Over the last few years, a similar trend can be seen in the emerging field of computational displays-spurred by the widespread availability of precise optical and material fabrication technologies; the research community has begun to investigate the joint design of display optics and computational processing. Such displays are not only designed for human observers but also for computer vision applications, providing high-dimensional structured illumination that varies in space, time, angle, and the color spectrum. This workshop is designed to unite the computational camera and display communities and in that it considers to what degree concepts from computational cameras can inform the design of emerging computational displays and vice versa, both focused on applications in computer vision.

Computational cameras and displays exploit the co-design of optical elements and computational processing to push the boundaries of conventional light acquisition and display systems. Submissions on all aspects of computational cameras and displays, especially exploring their duality, are encouraged:
Duality of Cameras and Displays:
Apply concepts and innovations developed for cameras to displays or the other way around, such as compressive displays or extended depth of field projection.
Explore imaging systems that combine light acquisition and display. Examples include projector-camera systems, light-sensitive displays, and unconventional camera flashlights.
Theoretical Analysis of Computational Cameras and Displays:
Establishing fundamental limits of different aspects of computational cameras and displays. New approaches to data processing, for instance using machine learning or compressive sensing.
Exotic Camera and Display Technologies:
Design of unconventional optics, sensors, light-emitters, or computational processing for imaging systems. Examples include systems inspired by biological visual systems, omni-vision displays, and single pixel cameras.
Perceptual Aspects of Computational Displays:
||Computational models for human perception, perceptually-driven computational displays, and all aspects of the human visual system relevant to computational displays.
Natural Image Statistics for Computational Cameras:
Mathematical priors that are exploited in the design of computational cameras, high-dimensional priors for natural scenes including the color spectrum, spatial, temporal, and directional light variation.
Visible Light Tomography in Computer Graphics .
Wolfgang Heidrich . University of British Columbia
Tomographic methods are the standard approach for obtaining volumetric measurements in medicine, science, and engineering. Typical tomography setups acquire 2D X-ray images of an object, and reconstruct a 3D voxel representation from this data. Unfortunately, for many applications in computer graphics, such X-ray setups are not feasible due to cost and/or safety concerns. In this presentation, I will introduce our recent work on visible light tomography, which has much more modest hardware requirements. I will discuss tomographic methods in the presence of refraction, and show applications to the scanning of transparent objects, and the capture of gas flows. I will also discuss first results on a new solver for generic tomography problems.
Professor Wolfgang Heidrich holds the Dolby Research Chair in Computer Science at the University of British Columbia. He received a PhD in Computer Science from the University of Erlangen in 1999, and then worked as a Research Associate in the Computer Graphics Group of the Max-Planck-Institute for Computer Science in Saarbrucken, Germany, before joining UBC in 2000. Heidrich's research interests lie at the intersection of computer graphics, computer vision, imaging, and optics. In particular, he has worked on High Dynamic Range imaging and display, image-based modeling, measuring, and rendering, geometry acquisition, GPU-based rendering, and global illumination. Heidrich has written over 100 refereed publications on these subjects and has served on numerous program committees. He was the program co-chair for Graphics Hardware 2002, Graphics Interface 2004, and the Eurographics Symposium on Rendering, 2006.

Light-field Displays in Perspective .
Michael Klug . Zebra Imaging . CTO & Co-Founder
Light-field 3D displays have been explored in many forms over the past 100+ years, from integral and lenticular photography and parallax panoramagrams to “holographic element” or “hogel”-based displays and multi-layer automultiscopic displays. This talk will consider some of the history of light-field displays, particularly in the context of holographic and quasi-holographic encoding, and contemporary advances, enabled by smaller updatable pixels, more sophisticated computational display algorithms, and the growing ubiquity and speed of computational hardware. We’ll look at examples of holographic light-field displays, consider initial successful applications, and contemplate challenges and some creative ideas for light-field display content creation, including the notion of the display as a capture device.
Michael Klug received a Bachelor of Science degree from MIT in 1989 and a Master of Science degree from the Spatial Imaging Group at the MIT Media Lab in 1991. From 1991 until 1997, Michael worked as a Research Scientist at the MIT Media Laboratory, focusing on design and development of 3D displays and holographic systems. During his tenure at MIT, he was responsible for basic technology development, prototype construction and demonstration, proposal generation and program budgeting and renewal, sponsor recruitment, coordination, presentations and demonstrations, and laboratory resource management and establishment of group research goals. He developed the basic technological predecessors of the systems now productized by Zebra Imaging and has served as a consultant to various companies, such as Polaroid Corporation, in related fields. He is recognized internationally as one of a handful of experts in the field of automated hologram printing technology. At Zebra Imaging, Michael is responsible for overall technology strategy, intellectual property development and management, and integration of R&D, business development, market research, and technology and product trajectories.
