Highlights of the visit
Dr. Harlyn Baker presented a tutorial on light-field capture approaches and EPI-based light-field analysis. Afterwards he explained and provided a hands-on demonstration of his own light-field capture setup consisting of an array of 6X6 cameras. These are connected to a 6 FPGA boards, each serving 6 cameras.
The 6 FPGS boards in turn send their data to a mini workstation, which combines the captured light field into a single stream which is transmitted to the user’s computer over a Thunderbolt interface. During the demonstration, we have captured a light-field video sequence of 5 seconds to perform further experiments on the material, which will be made available to all PROLIGHT participants. The sequences are captured at 60 FPS at a resolution of 752 X 480 for each camera.
Bio
Harlyn Baker has a long history in multiple-image computer vision, from early 3D modelling in Edinburgh, to stereo in his PhD at Champaign-Urbana and the Stanford AI Lab, a dozen years at SRI, where he co-developed Epipolar Plane Image (EPI) Analysis, and a dozen more at HP Labs.
Harlyn’s EPI work, called seminal, has been instrumental in most later developments on Light Field analysis, including Ray Space and Hogel formulations. On leaving Interval Research, he was co-founder of TYZX, joined HP Labs in 2000, where he designed and developed camera systems to support multi-view studies, demonstrated automultiscopic imaging and display systems for 3D interaction and immersive experiences, and has most recently been exploring how 3D capture can impact print photography. Harlyn just took an early retirement package from Hewlett Packard Laboratories, and by summer will take up a position at the University of Heidelberg.
